Subject: Fix constness of the fdt void pointer in fdt_getprop_u32_default
X-Git-Tag: v2011.12-rc1~221^2^2
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=07e12784966c1d61b07861e6971fb8750a2ecc0c;p=u-boot

Fix constness of the fdt void pointer in fdt_getprop_u32_default

The function fdt_getprop_u32_default doesn't modify the fdt, so it can use a
const void * for its fdt argument.
