Subject: [PATCH] sky2: use ALIGN() macro
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4a15d56f78936ec15a5d747546f25ace8fef9a03;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[PATCH] sky2: use ALIGN() macro

The ALIGN() macro in kernel.h does the same math that the
sky2 driver was using for padding.
