From 6748703856d461f8cd62b72ebca51040e06cb310 Mon Sep 17 00:00:00 2001 From: Stephen Kitt Date: Thu, 13 Aug 2020 18:02:22 +0200 Subject: hwmon: use simple i2c probe function 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.
