From: Rasmus Villemoes Date: Tue, 8 Dec 2015 14:25:16 +0000 (+0100) Subject: osd: fix signed char versus %02x issue X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9a2fcad8dce219df6cac3db91f373080f017856a;p=linux-beck.git osd: fix signed char versus %02x issue If char is signed and one of these bytes happen to have a value outside the ascii range, the corresponding output will consist of "ffffff" followed by the two hex chars that were actually intended. One way to fix it would be to change the casts to (u8*) aka (unsigned char*), but it is much simpler (and generates smaller code) to use the %ph extension which was created for such short hexdumps.
