Date: Thu, 6 Jan 2022 09:24:28 +0800 From: Jiasheng Jiang <jiasheng@...as.ac.cn> To: perex@...ex.cz, tiwai@...e.com, leon@...nel.org, broonie@...nel.org, joe@...ches.com Cc: alsa-devel@...a-project.org, linux-kernel@...r.kernel.org, Jiasheng Jiang <jiasheng@...as.ac.cn> Subject: [PATCH] ALSA: intel_hdmi: Check for error num after setting mask As the dma_supported() may fail, the dma_set_mask_and_coherent() may fail too. Therefore, it should be better to check it and return error if fails.
