If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann commit af15769ffab13d777e55fdef09d0762bf0c249c4 upstream. gcc-7 notices that the condition in mvs_94xx_command_active looks suspicious: drivers/scsi/mvsas/mv_94xx.c: In function 'mvs_94xx_command_active': drivers/scsi/mvsas/mv_94xx.c:671:15: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context] This was introduced when the mv_printk() statement got added, and leads to the condition being ignored. This is probably harmless. Changing '&&' to '&' makes the code look reasonable, as we check the command bit before setting and printing it.
