usb: fotg210-hcd: delete an incorrect bounds test

2024-01-08T10:29:47+00:00

[ Upstream commit 7fbcd195e2b8cc952e4aeaeb50867b798040314c ]

Here "temp" is the number of characters that we have written and "size"
is the size of the buffer.  The intent was clearly to say that if we have
written to the end of the buffer then stop.

However, for that to work the comparison should have been done on the
original "size" value instead of the "size -= temp" value.  Not only
will that not trigger when we want to, but there is a small chance that
it will trigger incorrectly before we want it to and we break from the
loop slightly earlier than intended.

This code was recently changed from using snprintf() to scnprintf().  With
snprintf() we likely would have continued looping and passed a negative
size parameter to snprintf().  This would have triggered an annoying
WARN().  Now that we have converted to scnprintf() "size" will never
drop below 1 and there is no real need for this test.  We could change
the condition to "if (temp <= 1) goto done;" but just deleting the test
is cleanest.

iio: adc: ti_am335x_adc: Fix return value check of tiadc_request_dma()

Fix wrong handling of a DMA request where the probing only failed
if -EPROPE_DEFER was returned. Instead, let us fail if a non -ENODEV
value is returned. This makes DMAs explicitly optional. Even if the
DMA request is unsuccessfully, the ADC can still work properly.
We do also handle the defer probe case by making use of dev_err_probe().

iio: common: ms_sensors: ms_sensors_i2c: fix humidity conversion time table

2024-01-08T10:29:46+00:00

commit 54cf39ec16335dadbe1ba008d8e5e98dae3e26f8 upstream.

The HTU21 offers 4 sampling frequencies: 20, 40, 70 and 120, which are
associated to an index that is used to select the right measurement
resolution and its corresponding measurement time. The current
implementation selects the measurement resolution and the temperature
measurement time properly, but it does not select the right humidity
measurement time in all cases.

In summary, the 40 and 70 humidity measurement times are swapped.

The reason for that is probably the unusual coding for the measurement
resolution. According to the datasheet, the bits [7,0] of the "user
register" are used as follows to select the bit resolution:

--------------------------------------------------
| Bit 7 | Bit 0 | RH | Temp | Trh (us) | Tt (us) |
--------------------------------------------------
|   0   |   0   | 12 |  14  |  16000   |  50000  |
--------------------------------------------------
|   0   |   1   | 8  |  12  |  3000    |  13000  |
--------------------------------------------------
|   1   |   0   | 10 |  13  |  5000    |  25000  |
--------------------------------------------------
|   1   |   1   | 11 |  11  |  8000    |  7000   |
--------------------------------------------------
*This table is available in the official datasheet, page 13/21. I have
just appended the times provided in the humidity/temperature tables,
pages 3/21, 5/21. Note that always a pair of resolutions is selected.

The sampling frequencies [20, 40, 70, 120] are assigned to a linear
index [0..3] which is then coded as follows [1]:

Index    [7,0]
--------------
idx 0     0,0
idx 1     1,0
idx 2     0,1
idx 3     1,1

That is done that way because the temperature measurements are being
used as the reference for the sampling frequency (the frequencies and
the temperature measurement times are correlated), so increasing the
index always reduces the temperature measurement time and its
resolution. Therefore, the temperature measurement time array is as
simple as [50000, 25000, 13000, 7000]

On the other hand, the humidity resolution cannot follow the same
pattern because of the way it is coded in the "user register", where
both resolutions are selected at the same time. The humidity measurement
time array is the following: [16000, 3000, 5000, 8000], which defines
the following assignments:

Index    [7,0]    Trh
-----------------------
idx 0     0,0     16000  -> right, [0,0] selects 12 bits (Trh = 16000)
idx 1     1,0     3000   -> wrong! [1,0] selects 10 bits (Trh = 5000)
idx 2     0,1     5000   -> wrong! [0,1] selects 8 bits (Trh = 3000)
idx 3     1,1     8000   -> right, [1,1] selects 11 bits (Trh = 8000)

The times have been ordered as if idx = 1 -> [0,1] and idx = 2 -> [1,0],
which is not the case for the reason explained above.

So a simple modification is required to obtain the right humidity
measurement time array, swapping the values in the positions 1 and 2.

The right table should be the following: [16000, 5000, 3000, 8000]

Fix the humidity measurement time array with the right idex/value
coding.

[1] The actual code that makes this coding and assigns it to the current
value of the "user register" is the following:
config_reg &= 0x7E;
config_reg |= ((i & 1) << 7) + ((i & 2) >> 1);

[ Upstream commit 08c94d80b2da481652fb633e79cbc41e9e326a91 ]

skb_share_check() already drops the reference to the skb when returning
NULL. Using kfree_skb() in the error handling path leads to an skb double
free.

Fix this by removing the variable tmp_skb, and return directly when
skb_share_check() returns NULL.
