Subject: [PATCH 2/2] Default all RPi 43455 boards to standard variant
As the patch above explains, the symlink that is being used by the
brcmfmac43455-sdio.* files is one that is created by the Debian system,
which we do not have in our implementation. Therefore, when the system
tries to load these files, an error message is generated.
By changing the symlinks to be to the standard variant, the problem is
solved for the build.
The code is also working without this patch - when the driver is unable
to load the board-specific file (such as
brcmfmac43455-sdio.raspberrypi,3-model-a-plus.bin), it reverts to using
the base file (brcmfmac43455-sdio.bin), which is a correct link (as it
is fixed in the patch above). However, the driver is still generating an
error message in this case, which is being solved by linking the
board-specific files to the standard variant as well.
Upstream-Status: Inappropriate [issue reported at https://github.com/RPi-Distro/firmware-nonfree/issues/26]
