Subject: [media] qt1010: do not change frequency during init
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7f12088798b671626b46ba77abee763d6348f146;p=linux-beck.git

[media] qt1010: do not change frequency during init

Changing cached frequency during init is something no-no.
Make it behave a little bit better. After that device could
survive from suspend/resume when streaming is ongoing.
