From: Amitkumar Karwar Date: Fri, 28 Feb 2014 03:35:16 +0000 (-0800) Subject: mwifiex: skipping pending commands after unload X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ace273551b7c9c2cfbfc606ac4cd518c67f80faf;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git mwifiex: skipping pending commands after unload We skip downloading other commands after FUNC_SHUTDOWN is queued during driver unload. Main thread should be woken up each time after freeing skipped command so that FUNC_SHUTDOWN gets served in case if there are other pending commands before FUNC_SHUTDOWN. Also, call mwifiex_complete_cmd() only for synchronous commands.
