Subject: SM501: reverse FPEN/VBIASEN flags behaviour
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cdc83ae2453ddb19060e05e6afd22b1254128c42;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

SM501: reverse FPEN/VBIASEN flags behaviour

To keep backwards compatibility, reverse the meanings of these flags so
that when they are not set, the driver uses the original behvaiour.
