[PATCH] media: iris: fix VPSS line buffer width and height order
From: Wangao Wang
Date: Mon Sep 21 2026 - 23:27:26 EST
size_vpss_line_buf_vpu33() expects (num_pipes, height, width) but was
called with width and height swapped, miscalculating VPSS line buffer
size for non-square resolutions.
Fixes: df816dce1b01 ("media: iris: Introduce buffer size calculations for vpu4")
