Re: compile error media-build on 4.15 because of 'device_get_match_data'
Hello! I just pushed a fix to media-build. But I had to disable the driver for Kernels older than 4.16. -> VIDEO_I2C requires device_get_match_data which requires the function pointer device_get_match_data in fwnode_operations. The latter has been added first in Kernel 4.16. If someone wants to have VIDEO_I2C in Kernels older than 4.16, please provide patch. BR, Jasmin
compile error media-build on 4.15 because of 'device_get_match_data'
I tried to compile media-build on Ubuntu 18.04. (gcc 7.3.0) with Kernel 4.15 and get this error: /home/martin/media_build/v4l/video-i2c.c: In function 'video_i2c_probe': /home/martin/media_build/v4l/video-i2c.c:456:16: error: implicit declaration of function 'device_get_match_data'; did you mean 'of_device_get_match_data'?
