Subject: Re: [PATCH v14 2/6] media: imagination: Add E5010 JPEG Encoder driver
Hey Devarsh,
This doesn't compile without errors for me, curious, it probably did
compile without problems for you right?
drivers/media/platform/imagination/e5010-jpeg-enc.c:1622:19: error: initialization of ‘int (*)(struct platform_device *)’ from incompatible pointer type ‘void (*)(struct platform_device *)’ [-Werror=incompatible-pointer-types]
1622 | .remove = e5010_remove,
| ^~~~~~~~~~~~
drivers/media/platform/imagination/e5010-jpeg-enc.c:1622:19: note: (near initialization for ‘e5010_driver.remove’)
cc1: some warnings being treated as errors
Regards,
Sebastian
