Silly nitpick. Looks like this is not defined yet?
I'm getting:
drivers/staging/media/hantro/hantro_drv.c:364:12: error: ‘HANTRO_HEVC_DECODER’ undeclared here (not in a function); did you mean
‘HANTRO_H264_DECODER’?
364 | .codec = HANTRO_HEVC_DECODER,
| ^~~~~~~~~~~~~~~~~~~
| HANTRO_H264_DECODER
I'll review the G2 driver soon :-)
Thanks,
Ezequiel
