When building with -Wsometimes-uninitialized, Clang warns: drivers/scsi/gdth.c:3662:6: warning: variable 'paddr' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] Don't attempt to call dma_free_coherent when buf is NULL (meaning that we never called dma_alloc_coherent and initialized paddr), which avoids this warning.

Switch from the legacy PCI DMA API to the generic DMA API. Also switch to dma_map_single from pci_map_page in one case where this makes the code simpler. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>

The non-PCI code has bitrotted for quite a while and will just oops on load because it passes a NULL pointer to the PCI DMA routines. Lets kill it for good - if someone really wants to use one of these cards I'll help mentoring them to write a proper driver glue.

Out of the three callers once insists on the scratch buffer, and the others are fine with a new allocation. Switch those two to just use pci_alloc_consistent directly, and open code the scratch buffer allocation in the remaining one. This avoids a case where we might be doing a memory allocation under a spinlock with irqs disabled. [mkp: typo] Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K.

This function is a huge mess with duplicated error handling. Split out a few useful helpers and use goto labels to untangle the error handling and no-data ioctl handling. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
