Subject: m68k: correct setting of struct user.u_ar0
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=145e9230760e4db27cf5f00fd04b005c79ca1c12;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

m68k: correct setting of struct user.u_ar0

Commit 6e16d89bcd668a95eb22add24c02d80890232b66 ("Sanitize the type of
struct user.u_ar0") forgot to change the m68k setting code, causing the
following compiler warning:

    arch/m68k/kernel/process.c:338: warning: assignment makes integer from pointer without a cast
