Subject: mwifiex: Do not kfree cmd buf while unregistering PCIe
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=955ab095c51a6f5a105aaeff4fc8e32c2ee94814;p=deliverable%2Flinux.git

mwifiex: Do not kfree cmd buf while unregistering PCIe

All the command buffers are freed in mwifiex_free_cmd_buffer()
and hence there is no need to kfree the current command buffer
again. This might ends up freeing memory allocated by some other
kernel code.
