2017-11-16hwmon: (w83791d) Remove duplicate NULL checkAndy Shevchenko1-10/+5
Since i2c_unregister_device() became NULL-aware we may remove duplicate NULL check.

2017-01-02hwmon: (w83791d) use permission-specific DEVICE_ATTR variantsJulia Lawall1-12/+11
Use DEVICE_ATTR_RO for read only attributes and DEVICE_ATTR_RW for read/write attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The conversion was done automatically using coccinelle. It was validated by compiling both the old and the new source code and comparing its text, data, and bss size.

smatch complains as follows when checking w83791d.c. drivers/hwmon/w83791d.c:996 store_temp23() warn: '32768' 32768 can't fit into 32767 'data->temp_add[nr][index]' Fix by using DIV_ROUND_CLOSEST and clamp_val to convert the values.

2013-01-25hwmon: Replace SENSORS_LIMIT with clamp_valGuenter Roeck1-5/+5

2012-11-05hwmon: Fix chip feature table headersJean Delvare1-1/+1
These got broken by recent patches fixing checkpatch warnings in these drivers. The trick is that the patches themselves looked good, but the source files after applying them do not. That's why I am not a big fan of using tabs inside comments. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <linux@roeck-us.net>

2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell1-2/+2
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2009-12-14i2c: Get rid of struct i2c_client_address_dataJean Delvare1-1/+1

2009-01-07hwmon: Don't overuse I2C_CLIENT_MODULE_PARMJean Delvare1-1/+4
I2C_CLIENT_MODULE_PARM is overkill for force_subclients. We really only use 4 out of the 48 slots, so we're better defining a custom variable instead.

2008-02-07hwmon: VRM is not written to registersJean Delvare1-4/+2
What was true of reading the VRM value is also true of writing it: not being a register value, it doesn't need hardware access, so we don't need a reference to the i2c client. This allows for a minor code cleanup. As gcc appears to be smart enough to simplify the generated code by itself, this cleanup only affects the source code, the generated binaries are unchanged.
