2020-09-23hwmon: use simple i2c probe functionStephen Kitt1-4/+5
Many hwmon drivers don't use the id information provided by the old i2c probe function, and the remainder can easily be adapted to the new form ("probe_new") by calling i2c_match_id explicitly. This avoids scanning the identifier tables during probes. Drivers which didn't use the id are converted as-is; drivers which did are modified as follows: * if the information in i2c_client is sufficient, that's used instead (client->name); * anything else is handled by calling i2c_match_id() with the same level of error-handling (if any) as before. A few drivers aren't included in this patch because they have a different set of maintainers. They will be covered by other patches.

2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell1-1/+1
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>
