Otherwise in worst case scenario the host may lock up. Instead of using sleeps and hoping the device is operational in some arbitrary timeframes use firmware indication register. As a side effect this makes driver boot/stop/recovery faster. Signed-off-by: Michal Kazior Signed-off-by: Kalle Valo --- Reading git-diff-tree failed
