Subject: leds: bcm6358: remove unneded lock when checking initial LED status
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=93a708dab8175c57977d5eec757dd559128f2353;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

leds: bcm6358: remove unneded lock when checking initial LED status

This lock isn't really needed, since we're only reading the register and
changes made to other LEDs aren't relevant.
