Subject: [media] omap3isp: Use external rate instead of vpcfg
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c6c01f97b1733ba110993ec51600c06961e41bfe;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[media] omap3isp: Use external rate instead of vpcfg

Access pipe->external_rate instead of isp_ccdc.vpcfg.pixelclk. Also remove
means to set the value for isp_ccdc_vpcfg.pixelclk.
