Subject: linux-next: build warning after merge of the wireless-drivers-next tree

Hi all,

After merging the wireless-drivers-next tree, today's linux-next build
(x86_64 allmodconfig) produced this warning:

drivers/net/wireless/marvell/mwifiex/pcie.c: In function 'mwifiex_pcie_remove':
drivers/net/wireless/marvell/mwifiex/pcie.c:303:5: warning: 'fw_status' may be used uninitialized in this function [-Wmaybe-uninitialized]
  if (fw_status == FIRMWARE_READY_PCIE && !adapter->mfg_mode) {
     ^

Introduced by commit

  045f0c1b5e26 ("mwifiex: get rid of global user_rmmod flag")

This is not a false positive since "reg" could be NULL just above
(otherwise it would be tested for).
