Subject: hwmon: (w83795) Move files removal to a separate function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2fa09878ba1dc458b8cb6e9c8fbc8f2e5401d2b2;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

hwmon: (w83795) Move files removal to a separate function

Sysfs files must be removed on device removal but also when device
registration fails. Move the code to a separate function to avoid
code redundancy.
