media: dvb-frontends/drxk_hard.c: fix uninitialized variable warningHEADmaster
drxk_hard.c: In function 'hi_command.constprop': drxk_hard.c:1016:5: warning: 'wait_cmd' may be used uninitialized in this function [-Wmaybe-uninitialized] 1015 | } while ((status < 0) && (retry_count < DRXK_MAX_RETRIES) | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1016 | && (wait_cmd != 0)); | ^~~~~~~~~~~~~~~~~~ The underlying cause is that the while condition is wrong. It should be: (status < 0 || wait_cmd) && (retry_count < DRXK_MAX_RETRIES) 'wait_cmd' is only valid if '!(status < 0)'.
