The patch ASoC: xlnx: fix error handling in xlnx_formatter_pcm_probe has been applied to the asoc tree at https://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 >From fbaa95f4397eef4448bf9dbc36b7d4e961b169a6 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" <gustavo@xxxxxxxxxxxxxx> Date: Wed, 26 Dec 2018 15:11:06 -0600 Subject: [PATCH] ASoC: xlnx: fix error handling in xlnx_formatter_pcm_probe Currently, if platform_get_irq_byname() fails, the returned error turns into a huge value, once it is being store into a variable of type unsigned int, hence never actually reporting any error and causing unexpected behavior when using the values stored in aud_drv_data->s2mm_irq and aud_drv_data->mm2s_irq. Fix this by changing the type of variables s2mm_irq and mm2s_irq in structure xlnx_pcm_drv_data from unsigned int to int.
