2010-10-28hwmon: (s3c-hwmon) Use a real mutexThomas Gleixner1-4/+4
The semaphore which protects the ADC is semantically a mutex. Use a real mutex. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2009-12-09hwmon: (s3c-hwmon) Fix build errorBen Dooks1-2/+2
The previous patch, commit be4c23c93c4828d36ac9e1a88410618a61676426 was from the wrong tree and thus broke the current build which had the channel configuration name changed. Fix the following build errors: drivers/hwmon/s3c-hwmon.c: In function 's3c_hwmon_probe': drivers/hwmon/s3c-hwmon.c:326: warning: initialization from incompatible pointer type drivers/hwmon/s3c-hwmon.c:331: error: dereferencing pointer to incomplete type drivers/hwmon/s3c-hwmon.c:336: error: dereferencing pointer to incomplete type Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2009-11-16hwmon: (s3c-hwmon) Ignore invalid divider settingsBen Dooks1-2/+9
Avoid registering channels that have zero divider settings in them, as this will only lead to kernel OOPS from divide-by-zero when the sysfs entry is read. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Jean Delvare <khali@linux-fr.org>
