2020-05-14video/hdmi: Add Unpack only function for DRM infoframeGwan-gyeong Mun1-19/+46
It adds an unpack only function for DRM infoframe for dynamic range and mastering infoframe readout. It unpacks the information data block contained in the binary buffer into a structured frame of the HDMI Dynamic Range and Mastering (DRM) information frame. In contrast to hdmi_drm_infoframe_unpack() function, it does not verify a checksum. It can be used for unpacking a DP HDR Metadata Infoframe SDP case. DP HDR Metadata Infoframe SDP uses the same Dynamic Range and Mastering (DRM) information (CTA-861-G spec.) such as HDMI DRM infoframe. But DP SDP header and payload structure are different from HDMI DRM Infoframe. Therefore unpacking DRM infoframe for DP requires skipping of a verifying checksum. v9: Add clear comments to hdmi_drm_infoframe_unpack_only() and hdmi_drm_infoframe_unpack() (Laurent Pinchart) Signed-off-by: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Reviewed-by: Uma Shankar <uma.shankar@intel.com> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200514060732.3378396-2-gwan-gyeong.mun@intel.com

Some memory is vmalloc'ed in the 'w100fb_save_vidmem' function and freed in the 'w100fb_restore_vidmem' function. (these functions are called respectively from the 'suspend' and the 'resume' functions) However, it is also freed in the 'remove' function. In order to avoid a potential double free, set the corresponding pointer to NULL once freed in the 'w100fb_restore_vidmem' function.
