Subject: ramoops: move dump_oops into platform data
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6b4d2a2733b9a17112f746d498c9f9a0427dcdd8;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ramoops: move dump_oops into platform data

The platform driver currently allows setting the mem_size and
mem_address.

ince dump_oops is also a module parameter it would be more consistent if
it could be set through platform data as well.
