* rtlwifi: rtl8192cu: Fix problem that prevents reassociationLarry Finger2013-03-13
| | | | | | | | | | | | | | | | | | | The driver was failing to clear the BSSID when a disconnect happened. That prevented a reconnection. This problem is reported at https://bugzilla.redhat.com/show_bug.cgi?id=789605, https://bugzilla.redhat.com/show_bug.cgi?id=866786, https://bugzilla.redhat.com/show_bug.cgi?id=906734, and https://bugzilla.kernel.org/show_bug.cgi?id=46171. Thanks to Jussi Kivilinna for making the critical observation that led to the solution.

* wireless: Remove casts to same typeJoe Perches2012-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding casts of objects to the same type is unnecessary and confusing for a human reader. For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force, __iomem and __user. @@ type T; T *p; @@ - (T *)p + p Neatened the mwifiex_deauthenticate_infra function which was doing odd things with array pointers and not using is_zero_ether_addr.

* rtlwifi: Convert to asynchronous firmware loadLarry Finger2012-01-30
| | | | | | | | | | | | | | | | | | | | | | | | 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 <Larry.Finger@lwfinger.net> Cc: Stable <stable@vger.kernel.org> Signed-off-by: John W.
