From: Thierry Escande Date: Fri, 30 Jun 2017 14:15:43 +0000 (-0400) Subject: media: s5p-jpeg: Don't use temporary structure in s5p_jpeg_buf_queue X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=14a2de14dc0619bf926c56cd12e29e0245d12abc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git media: s5p-jpeg: Don't use temporary structure in s5p_jpeg_buf_queue If s5p_jpeg_parse_hdr() fails to parse the JPEG header, the passed s5p_jpeg_q_data structure is not modified so there is no need to use a temporary structure and the field-by-field copy can be avoided.
