Subject: Use a const pointer for map_to_sysmem()
X-Git-Tag: v2014.04-rc3~56
X-Git-Url: https://git.kernelconcepts.de/?p=karo-tx-uboot.git;a=commitdiff_plain;h=66bd1cff901c5b19b351c7b5ad48cee09c15d992

Use a const pointer for map_to_sysmem()

This function does not actually change the pointer contents, so use const
so that functions which have a const pointer do not need to cast.
