[PATCH v2] drm/lsdc: Request PCI BAR

From: Philipp Stanner
Date: Mon Nov 25 2024 - 09:03:10 EST


lsdc currently just ioremaps its PCI BAR with pcim_iomap(). Performing
a region regquest additionally can make the driver more robust.

Replace pcim_iomap() with the managed function pcim_iomap_region() which
performs the request and ioremaps the BAR.
