hwmon: (f75375s) Fix automatic pwm mode setting for F75373 & F75375

2012-02-20T20:48:12+00:00

commit 09e87e5c4f9af656af2a8a3afc03487c5d9287c3 upstream.

In order to enable temperature mode aka automatic mode for the F75373 and
F75375 chips, the two FANx_MODE bits in the fan configuration register
need be set to 01, not 10.

hwmon: (f75375s) Fix bit shifting in f75375_write16

2012-02-20T20:48:10+00:00

commit eb2f255b2d360df3f500042a2258dcf2fcbe89a2 upstream.

In order to extract the high byte of the 16-bit word, shift the word to
the right, not to the left.

hwmon: (w83627ehf) Fix number of fans for NCT6776F

2012-02-13T19:06:10+00:00

commit 585c0fd8216e0c9f98e2434092af7ec0f999522d upstream.

NCT6776F can select fan input pins for fans 3 to 5 with a secondary set of
chip register bits. Check that second set of bits in addition to the first set
to detect if fans 3..5 are monitored.

hwmon: (w83627ehf) Disable setting DC mode for pwm2, pwm3 on NCT6776F

2012-02-03T17:19:01+00:00

commit ad77c3e1808f07fa70f707b1c92a683b7c7d3f85 upstream.

NCT6776F only supports pwm mode for pwm2 and pwm3. Return error if an attempt
is made to set those pwm channels to DC mode.

hwmon: (f71805f) Fix clamping of temperature limits

2012-02-03T17:19:01+00:00

commit 86b2bbfdbd1fcc4a3aa62ccd3f245c40c5ad5b85 upstream.

Properly clamp temperature limits set by the user. Without this fix,
attempts to write temperature limits above the maximum supported by
the chip (255 degrees Celsius) would arbitrarily and unexpectedly
result in the limit being set to 0 degree Celsius.

hwmon: (coretemp) Fix oops on CPU offlining

2011-12-21T20:57:41+00:00

This is for stable kernel branch 3.0 only. Previous and later versions
have different code paths and are not affected by this bug.

This is the same fix as "hwmon: (coretemp) Fix oops on driver load"
but for the CPU offlining case. Sorry for missing it at first.

hwmon: (jz4740) fix signedness bug

2011-12-21T20:57:39+00:00

commit 0b57d7602b68f7b2786b2f0e22da39cbd4139a95 upstream.

wait_for_completion_interruptible_timeout() may return negative value.
In this case, checking if (t > 0)  will return true if t is unsigned.

hwmon: (coretemp) Fix oops on driver load

2011-12-09T16:52:34+00:00

This is for stable kernel branch 3.0 only. Previous and later versions
have different code paths and are not affected by this bug.

If the CPU microcode is too old, the coretemp driver won't work. But
instead of failing gracefully, it currently oops. Check for NULL
platform device data to avoid this.

hwmon: (w83627ehf) Fix broken driver init

2011-11-11T17:37:00+00:00

commit bfa02b0da66965caf46e441270af87edda4fea14 upstream.

Commit 2265cef2 (hwmon: (w83627ehf) Properly report PECI and AMD-SI
sensor types) results in kernel panic if data->temp_label was not
initialized.
The problem was found with chip W83627DHG-P.

Add check if data->temp->label was set before use.

Based on incomplete patch by Alexander Beregalov.
