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

2012-02-20T20:46:17+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

2012-02-20T20:46:16+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

2012-02-13T19:16:58+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

2012-02-03T17:22:15+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

2012-02-03T17:22:15+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: (jz4740) Staticise jz4740_hwmon_driver

It is not used outside this driver so no need to make the symbol global.

hwmon: (jz4740) fix signedness bug

2011-12-12T16:31:21+00:00

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

hwmon: convert drivers/hwmon/* to use module_platform_driver()

2011-11-26T17:48:20+00:00

This patch converts the drivers in drivers/hwmon/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

hwmon: Remove redundant spi driver bus initialization

2011-11-25T15:48:16+00:00

In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_register_driver(),
so we can drop the manual assignment.

The patch was generated using the following coccinelle semantic patch:
// 
@@
identifier _driver;
@@
struct spi_driver _driver = {
	.driver = {
-		.bus = &spi_bus_type,
	},
};
//
