Subject: BUG_ON() Conversion in drivers/isdn
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6dd44a74469c203c5106ada2082c46267b4ac674;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

BUG_ON() Conversion in drivers/isdn

this changes if() BUG(); constructs to BUG_ON() which is
cleaner, contains unlikely() and can better optimized away.
