Thanks for the report. The fixes (see the mail from Laurent) apparently
are still not mainlined (or am I missing something?), so let me add this
report to the tracking to ensure this is not forgotten:

#regzbot ^introduced cf21f328fcaf
#regzbot fix: media: nxp: ignore unused suspend operations
#regzbot ignore-activity

(I simply picked the latter of the two fixes, that should do the trick)

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
