[alsa-devel] [PATCH v2 0/2] ASoC: qcom: fix static checker warnings.
This patchset fixes 2 static checker warnings reported by Dan Carpenter. Thanks, srini Srinivas Kandagatla (2): ASoC: qcom: Fix uninitialized symbol warning. ASoC: qcom: remove IS_ERR_VALUE usage on int. sound/soc/qcom/lpass-platform.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) -- 2.5.0
This patch fixes following static checker warning, by initializing the ret to -EINVAL, as one of the code path in lpass_platform_pcm_new() uses this variable uninitialized. sound/soc/qcom/lpass-platform.c:555 lpass_platform_pcm_new() error: uninitialized symbol 'ret'.

The patch ASoC: qcom: Fix uninitialized symbol warning. has been applied to the asoc tree at git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark
