If anyone has any objections, please let me know. ------------------ From: Suresh Reddy commit 4cad9f3b61c7268fa89ab8096e23202300399b5d upstream. On BE3, if the clear-interrupt bit of the EQ doorbell is not set the first time it is armed, ocassionally we have observed that the EQ doesn't raise anymore interrupts even if it is in armed state. This patch fixes this by setting the clear-interrupt bit when EQs are armed for the first time in be_open(). Signed-off-by: Suresh Reddy Signed-off-by: Sathya Perla Signed-off-by: David S.
