From f5b678d6dcba9c71870eab132dcb36daaffd5cf4 Mon Sep 17 00:00:00 2001 From: Lin Ma Date: Mon, 27 Jun 2011 18:53:59 -0700 Subject: [PATCH] Update to 5.90.125.32: * Move Android specific functions to wl_android (wifi control functions, wifi device, pre-alloc buffer.) * Link Android start/stop commands to interface up/down (download firmware when primary interfacde is up.) * Fix a issue in driver unload, the same IRQ can not be disabled twice (set_irq_wake) Change-Id: Id49c4f746f69371323c9a34834c3b628b78ff713 Signed-off-by: Howard M.
