Subject: [PATCH v5 1/5] Bluetooth: btmtk: add the function to get the fw name
Date: Wed, 15 May 2024 16:15:17 -0700 [thread overview]
Message-ID: <ce0337178bf617d52ff320a36837d75bf537df2d.1715813148.git.sean.wang@kernel.org> (raw)
From: Sean Wang <sean.wang@mediatek.com>
Include a shared function to get the firmware name, to prevent repeating
code for similar chipsets.
Signed-off-by: Sean Wang <sean.wang@mediatek.com>

v3: first added to the series
v4: rebase onto the latest code and add an additional parameter
fw_flavor into the function btmtk_fw_get_filename.
v5: fix an issue about the directive output truncated writing caught by
the linux test robot
