Setting context source and destination formats should only be done

Remove these calls from hantro_reset_encoded_fmt() and
hantro_reset_raw_fmt() to clean the driver.

KernelCI found this patch causes a regression in the
baseline.dmesg.alert test [1] on rk3399-rock-pi-4b [2],
see the bisection report for more details [3].

Let us know if you have any questions.

Thx for the report. FWIW, regzbot noticed there is a patch that refers
to the culprit that might have been landed in next after your test ran
for the last time (and meanwhile it was mainlined): f100ce3bbd6 ("media:
verisilicon: Fix crash when probing encoder")

Yes that patch should fix the probing issue.
Marek is working on an additional one to fix pixel format negotiation
but that doesn't impact the boot.

Regards,
Benjamin


I wonder if that is related or might even fix the issue.

Ciao, Thorsten
