OMAP: SPI: Fix the trying to free nonexistent resource error
commit 1458d160de3f1862aeaac57447ba96e7857ac52b upstream.
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.
