Subject: m68k/q40: Add missing platform check before registering platform devices
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=450aed725c9a53282483c48ebd012feefae94a07;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

m68k/q40: Add missing platform check before registering platform devices

On multi-platform kernels, the Q40/Q60 platform devices should be
registered when running on Q40/Q60 only. Else it may crash later.
