Subject: Re: [PATCH -next] media: chips-media: VIDEO_WAVE_VPU should depend
 on ARCH_K3

Hey Geert,

Thanks for the patch!

Could you please adjust the subject line to:
media: chips-media: wave5: VIDEO_WAVE_VPU should depend on ARCH_K3
                     ^^^^^^

While it is true that is currently only tested on the K3 architecture ,
it is not only supported by that exact SoC, as you can see here:
https://lore.kernel.org/all/20231127223718.2651185-4-b-brnich@ti.com/T/

So, maybe this commit is worded better with:

is currently only supported on the Texas Instruments K3 architecture.

The change however is obviously correct.

Greetings,
Sebastian
