Subject: powerpc: Remove big endianness assumption in of_find_next_cache_node
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=afaf53985431bb295e4b723b08a55d0540cf8070;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

powerpc: Remove big endianness assumption in of_find_next_cache_node

Currently big endianness of the device tree data is assumed in
of_find_next_cache_node for 'handle' when calling of_find_node_by_phandle.

In preparation to move this function to common code, this patch fixes
the endianness using 'be32_to_cpup'
