From: Guennadi Liakhovetski Date: Mon, 8 Oct 2012 13:02:55 +0000 (-0300) Subject: [media] media: soc-camera: remove superfluous JPEG checking X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cea4c9e46c4f656a81c93f09b5e3bde38bebb160;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [media] media: soc-camera: remove superfluous JPEG checking Explicit checks for the JPEG pixel format in soc_mbus_bytes_per_line() and soc_mbus_image_size() are superfluous, because also without them these functions will perform correctly. The former will return 0 based on packing == SOC_MBUS_PACKING_VARIABLE and the latter will simply multiply the user-provided line length by the image height to obtain a frame buffer size estimate. The original version of the "media: soc_camera: don't clear pix->sizeimage in JPEG mode" patch was correct and my amendment, adding these two checks was superfluous.
