Subject: [PATCH 0/4] marvell: Fix firmware filenames for sd8977/sd8997 chipsets

This patch series fixes mwifiex and btmrvl drivers to load firmware for sd8977
and sd8997 chipsets from correct filename.

Both Marvell distribution package and linux-firmware repository [1] contain
firmware for these chipsets in files sdsd8977_combo_v2.bin/sdsd8997_combo_v4.bin.

Linux drivers mwifiex and btmrvl try to load firmware for these chipsets from
sd8977_uapsta.bin/sd8997_uapsta.bin files which obviously fails as these files
do not exist neither in linux-firmware [1] nor in Marvell distribution packages.

So the result is that Marvell sd8977 and sd8997 chipsets via mainline kernel
drivers (mwifiex and btmrvl) do not work out of box.

Each patch in this series fixes particular git commit which introduced usage
of incorrect firmware filename. Also each patch contains Fixes: line for easier
backporting to stable kernels.

mwifiex (1/4, 2/4) and btmrvl (3/4, 4/4) parts of this patch series can be
applied separately via wireless and bluetooth trees. I'm sending all four
patches in one patch series for easier review.
