Subject: arm64/include/asm: Fixed a warning about 'struct pt_regs'
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=af2c632e234f7158e891c27cc2270f8843f08855;p=linux-beck.git

arm64/include/asm: Fixed a warning about 'struct pt_regs'

If I include asm/irq.h on the top of my code, and set ARCH=arm64,
I'll get a compile warning, details are below:
warning: ‘struct pt_regs’
declared inside parameter list [enabled by default]

This patch is suggested by Arnd, see:
