[PATCH 5.8 006/177] regulator: remove superfluous lock in regulator_resolve_coupling()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Michał Mirosław <mirq-linux@xxxxxxxxxxxx>

[ Upstream commit a577f3456c0a2fac3dee037c483753e6e68f3e49 ]

The code modifies rdev, but locks c_rdev instead. Remove the lock
as this is held together by regulator_list_mutex taken in the caller.

Fixes: f9503385b187 ("regulator: core: Mutually resolve regulators coupling")
