staging: sm750fb: add missing pci_release_region on error and removal

2026-03-19T15:08:35+00:00

commit 8225489ddb900656cc21573b4e1b00c9181fd777 upstream. hw_sm750_map() calls pci_request_region() but never releases the region on error paths or in lynxfb_pci_remove(). This causes a resource leak that prevents the PCI region from being mapped again after driver removal or a failed probe. A TODO comment in the code acknowledges this missing cleanup. Restructure the error handling in hw_sm750_map() to properly release the PCI region on ioremap failures, and add pci_release_region() to lynxfb_pci_remove().

staging: sm750fb: remove unnecessary volatile qualifiers

2025-09-12T13:54:01+00:00

The use of 'volatile' for memory-mapped I/O pointers is discouraged in the Linux kernel as per Documentation/process/volatile-considered-harmful.rst. This patch removes the unnecessary 'volatile' qualifiers from the lynx_accel struct members, improving code quality and maintainability.
