* regulator: stpmic1: Fix kernel-doc notation warningsJiapeng Chong2023-11-131-1/+1
| | | | | | | | | | | | No functional modification involved. drivers/regulator/stpmic1_regulator.c:31: warning: expecting prototype for struct stpmic1. Prototype was for struct stpmic1_regulator_cfg instead. Reported-by: Abaci Robot <abaci@linux.alibaba.com> Closes: https://bugzilla.openanolis.cn/show_bug.cgi?id=7206 Signed-off-by: Jiapeng Chong <jiapeng.chong@linux.alibaba.com> Link: https://lore.kernel.org/r/20231109073925.98783-1-jiapeng.chong@linux.alibaba.com Signed-off-by: Mark Brown <broonie@kernel.org>
* regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers between 4.19 and 5.4Douglas Anderson2023-03-201-0/+1
| | | | | | | | | | This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in 4.14") but changes regulators didn't exist in Linux 4.19 but did exist in Linux 5.4.

* regulator: Use of_property_read_bool() for boolean propertiesRob Herring2023-03-111-1/+1
| | | | | | | | | | | It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. Convert reading boolean properties to to of_property_read_bool().

* regulator: remove locking around regulator_notifier_call_chain()Michał Mirosław2020-09-071-4/+0
| | | | | | | | | | | regulator_notifier_call_chain() doesn't need rdev lock and rdev's existence is assumed in the code anyway. Remove the locks from drivers.

| | | | | | | | | | | | | | In kerneldoc format, data structures have to start with 'struct' else the kerneldoc tooling/parsers/validators get confused.
