msm: vidc: Vote for buses immediately after allocing and freeing ocmem (903f112c) · Commits · e / devices / samsung / android_kernel_samsung_msm8916

Currently, ocmem bus is voted for accidently when vote_buses is called as part of a qbuf or a dqbuf. However, this relies on some other driver helpfully voting for the bus so that Venus isn't blocked on processing a frame. The Venus driver needs to vote the ocmem bus well before Venus does anything with ocmem, as such vote immediately after allocating ocmem.
