Subject: Re: [PATCH v10 00/18] Qualcomm video decoder/encoder driver
Hi Mauro,
One note, I have sent pull request for the firmware but forgot to update
the firmware path in the driver for the new location. It is not a big
deal, but I have to send one more patch which changes the firmware path.
About COMPILE_TEST, the patch for qcom_scm driver probably will be taken
in 4.13 merge window through arm-soc. So I'm wondering could you
postpone 18/18 until this patch is merged to avoid build breakage.
regards,
Stan
