From 12488e01fb2b06bb3f6ee137efc88e29d827817e Mon Sep 17 00:00:00 2001 From: Nishant Sarmukadam Date: Fri, 8 Apr 2011 14:38:27 +0530 Subject: [PATCH] mwl8k: interrupt handling changes We do not need to enable all the interrupts in mwl8k_probe_hw. We need to enable only MWL8K_A2H_INT_OPC_DONE interrupt for sending commands to the firmware. Keep the other interrupts masked in mwl8k_probe_hw. Also, in mwl8k_start, where we expect other interrupts, enable only those interrupts we are interested in. Signed-off-by: Nishant Sarmukadam Signed-off-by: John W.
