[PATCH 13/30] video/s3c: move platform_data out of arch/arm

Wed Apr 10 20:04:55 EDT 2013


The s3c-fb driver requires header files from the samsung platforms
to find its platform_data definition, but this no longer works on
multiplatform kernels, so let's move the data into a new header
file under include/linux/platform_data.
