media: v4l2-common: fix a compilation breakage
Clearly, changeset 95ce9c28601a ("media: v4l: common: Add a function to obtain best size from a list") was never tested, as it broke compilation with: drivers/media/platform/vivid/vivid-vid-cap.c: In function ‘vivid_try_fmt_vid_cap’: drivers/media/platform/vivid/vivid-vid-cap.c:565:34: error: macro "v4l2_find_nearest_size" requer 6 argumentos, mas apenas 5 foram fornecidos mp->width, mp->height); ^ drivers/media/platform/vivid/vivid-vid-cap.c:564:4: error: ‘v4l2_find_nearest_size’ undeclared (first use in this function); did you mean ‘__v4l2_find_nearest_size’? v4l2_find_nearest_size(webcam_sizes, width, height, ^~~~~~~~~~~~~~~~~~~~~~ __v4l2_find_nearest_size drivers/media/platform/vivid/vivid-vid-cap.c:564:4: note: each undeclared identifier is reported only once for each function it appears in drivers/media/i2c/ov5670.c: In function ‘ov5670_set_pad_format’: drivers/media/i2c/ov5670.c:2233:48: error: macro "v4l2_find_nearest_size" requer 6 argumentos, mas apenas 5 foram fornecidos fmt->format.width, fmt->format.height); ^ drivers/media/i2c/ov5670.c:2232:9: error: ‘v4l2_find_nearest_size’ undeclared (first use in this function); did you mean ‘__v4l2_find_nearest_size’? mode = v4l2_find_nearest_size(supported_modes, width, height, ^~~~~~~~~~~~~~~~~~~~~~ __v4l2_find_nearest_size drivers/media/i2c/ov13858.c: In function ‘ov13858_set_pad_format’: drivers/media/i2c/ov13858.c:1379:48: error: macro "v4l2_find_nearest_size" requer 6 argumentos, mas apenas 5 foram fornecidos fmt->format.width, fmt->format.height); ^ drivers/media/i2c/ov13858.c:1378:9: error: ‘v4l2_find_nearest_size’ undeclared (first use in this function); did you mean ‘__v4l2_find_nearest_size’? mode = v4l2_find_nearest_size(supported_modes, width, height, ^~~~~~~~~~~~~~~~~~~~~~ __v4l2_find_nearest_size drivers/media/i2c/ov13858.c:1378:9: note: each undeclared identifier is reported only once for each function it appears in Basically, v4l2_find_nearest_size() callers pass 5 arguments, while its definition require 6 args. Unfortunately, my build process was also broken, as it was reporting me that the compilation went fine: $ make ARCH=i386 CF=-D__CHECK_ENDIAN__ CONFIG_DEBUG_SECTION_MISMATCH=y C=1 W=1 CHECK='compile_checks' M=drivers/staging/media $ make ARCH=i386 CF=-D__CHECK_ENDIAN__ CONFIG_DEBUG_SECTION_MISMATCH=y C=1 W=1 CHECK='compile_checks' M=drivers/media *** ERRORS *** *** WARNINGS *** compilation succeeded That was due to a change here to use of linux-log-diff script that provides a diffstat between the errors output. Somehow, the logic was missing some fatal errors.
