Subject: f_rockusb: Use NULL instead of 0 for pointers
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=0234609d9631652e2faf77e23f332be29570d7d2;p=u-boot.git

f_rockusb: Use NULL instead of 0 for pointers

get_rkusb() mistakenly uses integers without cast.
Convert them to proper type.
