* watchdog: nowayout is boolWim Van Sebroeck2012-03-27
| | | | | | | nowayout is actually a boolean value. So make it bool for all watchdog device drivers. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

* hwmon: convert drivers/hwmon/* to use module_i2c_driver()Axel Lin2012-03-18
| | | | | | | | | | | | | | | | | | This patch converts the drivers in drivers/hwmon/* to use the module_i2c_driver() macro which makes the code smaller and a bit simpler.

* hwmon: (fschmd) Drop useless mutexJean Delvare2011-01-12
| | | | | | | | | | | | | | | | As discussed one year ago, the WDIOC_GETSUPPORT ioctl only needs a mutex because it operates on a static variable. There is no good reason to keep this variable static, so let's just make it non-static and drop the now useless mutex altogether.

* drivers: autoconvert trivial BKL users to private mutexArnd Bergmann2010-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All these files use the big kernel lock in a trivial way to serialize their private file operations, typically resulting from an earlier semi-automatic pushdown from VFS. None of these drivers appears to want to lock against other code, and they all use the BKL as the top-level lock in their file operations, meaning that there is no lock-order inversion problem. Consequently, we can remove the BKL completely, replacing it with a per-file mutex in every case. Using a scripted approach means we can avoid typos. These drivers do not seem to be under active maintainance from my brief investigation. Apologies to those maintainers that I have missed. file=$1 name=$2 if grep -q lock_kernel ${file} ; then if grep -q 'include.*linux.mutex.h' ${file} ; then sed -i '/include.*<linux\/smp_lock.h>/d' ${file} else sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file} fi sed -i ${file} \ -e "/^#include.*linux.mutex.h/,$ { 1,/^\(static\|int\|long\)/ { /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex); } }" \ -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \ -e '/[ ]*cycle_kernel_lock();/d' else sed -i -e '/include.*\<smp_lock.h\>/d' ${file} \ -e '/cycle_kernel_lock()/d' fi Signed-off-by: Arnd Bergmann <arnd@arndb.de>

* hwmon: Fix off-by-one kind valuesJean Delvare2010-03-05

* hwmon: (fschmd) Fix a memleak on multiple opens of /dev/watchdogHans de Goede2010-01-25
| | | | | | | | | When /dev/watchdog gets opened a second time we return -EBUSY, but we already have got a kref then, so we end up leaking our data struct. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: stable@kernel.org
* i2c: Drop I2C_CLIENT_INSMOD_2 to 8Jean Delvare2009-12-14
| | | | | | | | | These macros simply declare an enum, so drivers might as well declare it themselves. This puts an end to the arbitrary limit of 8 chip types per i2c driver. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
* i2c: Get rid of struct i2c_client_address_dataJean Delvare2009-12-14
| | | | | | | | | Struct i2c_client_address_data only contains one field at this point, which makes its usefulness questionable. Get rid of it and pass simple address lists around instead. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
* i2c: Drop the kind parameter from detect callbacksJean Delvare2009-12-14
| | | | | | | | The "kind" parameter always has value -1, and nobody is using it any longer, so we can remove it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
