X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8fbebb091a1695b8896597573c2d75831e41929a;p=linux-beck.git Staging: bcm: Alter code to move error handling closer to the calls. This is a cleanup patch. I've shuffled the code around to move the error handling closer to the calls. I've removed some indent levels. I've replaced break statements with direct returns.
