From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx> Subject: ide/falcon: remove in_interrupt() usage falconide_get_lock() is called by ide_lock_host() and its caller (ide_issue_rq()) has already a might_sleep() check. stdma_lock() has wait_event() which also has a might_sleep() check. Remove the in_interrupt() check. Link: https://lkml.kernel.org/r/20201113161021.2217361-2-bigeasy@xxxxxxxxxxxxx Signed-off-by: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx> Cc: "David S.
