Bottomley <JBottomley@xxxxxxxxxxxxx> Cc: David Howells <dhowells@xxxxxxxxxx>, Nick Cheng <nick.cheng@xxxxxxxxxxxx>, , kernel-janitors@xxxxxxxxxxxxxxx Subject: [patch] [SCSI] arcmsr: fix misuse of | instead of & Date: Sat, 9 Jun 2012 12:10:19 +0300 ARCMSR_ARC1880_DiagWrite_ENABLE is 0x00000080 so (x | 0x00000080) is never zero. The intent here was to test that loop until ARCMSR_ARC1880_DiagWrite_ENABLE was turned on, but because the test was wrong, we would do five loops regardless of whether it succeed or not. Also I simplified the condition a little by removing the unused assignement. Signed-off-by: Dan Carpenter <dan.carpenter@xxxxxxxxxx> --- Static checker stuff.
