I'm pretty tired of seeing these in my kernel compiles: drivers/mmc/card/block.c: In function ‘mmc_blk_issue_secdiscard_rq’: drivers/mmc/card/block.c:911:18: warning: ‘arg’ may be used uninitialized in this function [-Wuninitialized] drivers/mmc/card/block.c:910:6: warning: ‘nr’ may be used uninitialized in this function [-Wuninitialized] drivers/mmc/card/block.c:910:6: warning: ‘from’ may be used uninitialized in this function [-Wuninitialized]
This patch marks the variables explicitly uninitialized as seems to be the intention, I can assure myself they are not actually uninitialized at use time by just reading the code.
