[v1] tegra-video: add CSI support for Tegra20 and Tegra30

[PATCH v1 16/19] staging: media: tegra-video: tegra20: adjust luma buffer stride

Posted by Svyatoslav Ryhel 1 month, 2 weeks ago

Luma buffer stride is calculated by multiplying height in pixels of image
by bytes per line. Adjust that value accordingly.
