HID: make arrays usage and value to be the same

2021-02-26T09:08:37+00:00

commit ed9be64eefe26d7d8b0b5b9fa3ffdf425d87a01f upstream.

The HID subsystem allows an "HID report field" to have a different
number of "values" and "usages" when it is allocated. When a field
struct is created, the size of the usage array is guaranteed to be at
least as large as the values array, but it may be larger. This leads to
a potential out-of-bounds write in
__hidinput_change_resolution_multipliers() and an out-of-bounds read in
hidinput_count_leds().

To fix this, let's make sure that both the usage and value arrays are
the same size.

HID: wacom: Correct NULL dereference on AES pen proximity

2021-01-26T10:53:53+00:00

The recent commit to fix a memory leak introduced an inadvertant NULL
pointer dereference. The `wacom_wac->pen_fifo` variable was never
intialized, resuling in a crash whenever functions tried to use it.
Since the FIFO is only used by AES pens (to buffer events from pen
proximity until the hardware reports the pen serial number) this would
have been easily overlooked without testing an AES device.

This patch converts `wacom_wac->pen_fifo` over to a pointer (since the
call to `devres_alloc` allocates memory for us) and ensures that we assign
it to point to the allocated and initalized `pen_fifo` before the function
returns.

HID: multitouch: Apply MT_QUIRK_CONFIDENCE quirk for multi-input devices

2021-01-25T08:34:15+00:00

Palm ejection stops working on some Elan and Synaptics touchpad after
commit 40d5bb87377a ("HID: multitouch: enable multi-input as a quirk for
some devices").

The commit changes the mt_class from MT_CLS_WIN_8 to
MT_CLS_WIN_8_FORCE_MULTI_INPUT, so MT_QUIRK_CONFIDENCE isn't applied
anymore.

So also apply the quirk since MT_CLS_WIN_8_FORCE_MULTI_INPUT is
essentially MT_CLS_WIN_8.

HID: logitech-hidpp: Add product ID for MX Ergo in Bluetooth mode

2021-01-14T12:27:35+00:00

The Logitech MX Ergo trackball supports HID++ 4.5 over Bluetooth. Add its
product ID to the table so we can get battery monitoring support.
(The hid-logitech-hidpp driver already recognizes it when connected via
a Unifying Receiver.)

HID: sfh: fix address space confusion

2021-01-04T15:08:12+00:00

The new driver uses a phys_addr_t to store a DMA address,
which does not work when the two are different size:

Change both the type and the variable name to dma_addr for consistency.
