From b0302aba812bcc39291cdab9ad7e37008f352a91 Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Mon, 30 Jan 2012 09:54:49 -0600 Subject: rtlwifi: Convert to asynchronous firmware load This patch addresses a kernel bugzilla report and two recent mail threads. The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632, which reports a udev timeout on boot. The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/ linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a suspend/resume cycle for rtl8192cu. The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2) concerned changes in udev that break drivers that delay while firmware is loaded on modprobe. This patch converts all rtlwifi-based drivers to use the asynchronous firmware loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common callback routine. Driver rtl8192se needs different handling of the firmware, thus it has its own code. Signed-off-by: Larry Finger Cc: Stable Signed-off-by: John W.
