OMAP: SPI: Fix the trying to free nonexistent resource error
Currently there is a request_mem_region(r->start, .. followed by r->start += pdata->regs_offset; And then in remove r = platform_get_resource(pdev, IORESOURCE_MEM, 0); release_mem_region(r->start, resource_size(r)); Here the offset addition is not taken care. Fix the code for the same. Signed-off-by: Shubhrajyoti D <shubhrajyoti@ti.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
