[ Upstream commit 9733862e50fdba55e7f1554e4286fcc5302ff28e ] Commit f959dcd6ddfd29235030e8026471ac1b022ad2b0 (dma-direct: Fix potential NULL pointer dereference) added a null check on the dma_mask pointer of the kernel's device structure. Add a dma_mask variable to the ps3_dma_region structure and set the device structure's dma_mask pointer to point to this new variable. Fixes runtime errors like these: # WARNING: Fixes tag on line 10 doesn't match correct format # WARNING: Fixes tag on line 10 doesn't match correct format ps3_system_bus_match:349: dev=8.0(sb_01), drv=8.0(ps3flash): match WARNING: CPU: 0 PID: 1 at kernel/dma/mapping.c:151 .dma_map_page_attrs+0x34/0x1e0 ps3flash sb_01: ps3stor_setup:193: map DMA region failed Signed-off-by: Geoff Levand <geoff@infradead.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/562d0c9ea0100a30c3b186bcc7adb34b0bbd2cd7.1622746428.git.geoff@infradead.org Signed-off-by: Sasha Levin <sashal@kernel.org> |
