Subject: media: ti-vpe: cal: Iterate over correct number of CAMERARX instances Author: Laurent Pinchart <[email protected]> Date: Mon Dec 7 00:53:35 2020 +0100 When performing operations on all CAMERARX instances, code usually iterates over all cal->phy[] entries and skips the NULL pointers. The number of available CAMERARX instances is however available through cal->data->num_csi2_phy. Use it instead.
