From 2d0769387594eb26df33c72c08c6429e4fddf5fd Mon Sep 17 00:00:00 2001 From: Rosen Penev Date: Sun, 19 Jul 2026 17:09:29 -0700 Subject: [PATCH] ALSA: sis7019: Use pcim_iomap_region() for MMIO BAR Replace the open-coded pcim_request_all_regions() + devm_ioremap() pair with per-BAR pcim helpers: reserve BAR0 (the I/O port region, used via inl/outl) with pcim_request_region(), and reserve + iomap BAR1 (MMIO) with a single pcim_iomap_region() call. This folds the BAR1 reserve and iomap into one managed call. The error check moves from a NULL test to IS_ERR(), since pcim_iomap_region() returns an IOMEM_ERR_PTR on failure.
