Subject: [PATCH] firmware_loader: Fix labels with comma for builtin firmware
Date: Fri, 15 Nov 2019 23:59:11 +0100 [thread overview]
Message-ID: <20191115225911.3260-1-linus.walleij@linaro.org> (raw)
Some firmware images contain a comma, such as:
EXTRA_FIRMWARE "brcm/brcmfmac4334-sdio.samsung,gt-s7710.txt"
as Broadcom firmware simply tags the device tree compatible
string at the end of the firmware parameter file. And the
compatible string contains a comma.
This doesn't play well with gas:
drivers/base/firmware_loader/builtin/brcm/brcmfmac4334-sdio.samsung,gt-s7710.txt.gen.S: Assembler messages:
drivers/base/firmware_loader/builtin/brcm/brcmfmac4334-sdio.samsung,gt-s7710.txt.gen.S:4: Error: bad instruction `_fw_brcm_brcmfmac4334_sdio_samsung,gt_s7710_txt_bin:'

make[6]: *** [../scripts/Makefile.build:357: drivers/base/firmware_loader/builtin/brcm/brcmfmac4334-sdio.samsung,gt-s7710.txt.gen.o] Error 1
We need to get rid of the comma from the labels used by the
assembly stub generator.
Replacing a comma using GNU Make subst requires a helper
variable.
