Subject: [media] smiapp-pll: Don't validate OP clocks if there are none
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=63516b55e3efed3a306ada6f79aa7052c83249ce;p=deliverable%2Flinux.git

[media] smiapp-pll: Don't validate OP clocks if there are none

For profile 0 sensors (which have no OP clocks), the OP limits are in fact
VT limits. Do not verify them again.
