This is a note to let you know that I've just added the patch titled clk/sophgo: Using BUG() instead of unreachable() in mmux_get_parent_id() to the 6.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: clk-sophgo-using-bug-instead-of-unreachable-in-mmux_.patch and it can be found in the queue-6.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 2ad93e5a777abc3e3629c402c47f7ecb441d847e Author: Li Qiang <liqiang01@xxxxxxxxxx> Date: Tue Jul 9 14:36:38 2024 +0800 clk/sophgo: Using BUG() instead of unreachable() in mmux_get_parent_id() [ Upstream commit 1f7a04a0e673c19cc10bf4039047e11367ac5735 ] In general it's a good idea to avoid using bare unreachable() because it introduces undefined behavior in compiled code. but it caused a compilation warning, Using BUG() instead of unreachable() to resolve compilation warnings. Fixes the following warnings: drivers/clk/sophgo/clk-cv18xx-ip.o: warning: objtool: mmux_round_rate() falls through to next function bypass_div_round_rate() Fixes: 80fd61ec46124 ("clk: sophgo: Add clock support for CV1800 SoC") Signed-off-by: Li Qiang <liqiang01@xxxxxxxxxx> Link: https://lore.kernel.org/r/c8e66d51f880127549e2a3e623be6787f62b310d.1720506143.git.liqiang01@xxxxxxxxxx Signed-off-by: Stephen Boyd <sboyd@xxxxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> diff --git a/drivers/clk/sophgo/clk-cv18xx-ip.c b/drivers/clk/sophgo/clk-cv18xx-ip.c index 805f561725ae..b186e64d4813 100644 --- a/drivers/clk/sophgo/clk-cv18xx-ip.c +++ b/drivers/clk/sophgo/clk-cv18xx-ip.c @@ -613,7 +613,7 @@ static u8 mmux_get_parent_id(struct cv1800_clk_mmux *mmux) return i; } - unreachable(); + BUG(); } static int mmux_enable(struct clk_hw *hw)
