Hardik Phalet 448aaf54d3 fbdev: hgafb: Request memory region before ioremap 
The driver calls ioremap() on the HGA video memory at 0xb0000 without
first reserving the physical address range. This leaves the kernel
resource tree incomplete and can cause silent conflicts with other
drivers claiming the same range.

Add a devm_request_mem_region() call before ioremap() in
hga_card_detect() to reserve the memory region.
