Subject: [PATCH v3] staging: rtl8723bs: remove re-positioned call to kfree in
 os_dep/ioctl_cfg80211.c

A kernel cloned from git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git and built with the latest RTL8723BS driver included (CONFIG_RTL8723BS=m) fails when booting on an Intel Atom device with the RTL8723BS wifi chipset due to an error in drivers/staging/rtl8723bs/os_dep/ioctl_cfg80211.c.

The kernel when booted with Ubuntu 17.04 results in an unusable system however with the following patch booting is successful and the system is usable. The patch and kernel builds have been tested against on an Intel Compute Stick (STCK1A32WFC model).

This version of the patch (version 3) has tabs rather than spaces and no wrap around. The patch has received one review:

Patch looks good to me:
