mchehab: can you apply this patch? https://patchwork.linuxtv.org/project/linux-media/patch/7a17b41b-f7e2-268e-36fa-deae431454a4@xs4all.nl/ Without it I can't enable vidtv with 'make menuconfig'. hverkuil: thanks for reporting it so quickly! patch applied Thanks! I'll enable it for the next daily build. ok, thanks! btw, it will produce some pr_fmt() warnings at media_build I'm considering changing pr_foo() to dev_foo() there instead of fixing media_build it's very easy to fix media_build, so don't bother on my account. mchehab: I'm getting warnings in vidtv when compiling for 32 bit. Replied to the cover letter with the warnings. 64 bit is fine. Also fixed media_build. hverkuil: well, the thing is that I prefer using dev_foo instead of pr_foo :-) anyway, at least some of them will be painful to replace btw, I expect it may have troubles building on random archs as the files aren't including kernel.h, but instead several headers like linux/printk.h I'll address the 32 bit ones and probably do some cleanups at includes 32-bit warnings fixed speaking of media_build, I've had a crash recently caused by dma-buf.h being copied from the media tree I'm running kernel v5.4.60 and in the latest kernel dma_buf_ops has gained a few new operations the dmabuf core can't be compiled as a module, so it runs with the v5.4.60 version of that structure while media_build uses a newer version that doesn't work well quite obviously
