Russell Currey 66469319c0 drivers/gpu/drm/ast: Fix infinite loop if read fails ... commit 298360af3d upstream. ast_get_dram_info() configures a window in order to access BMC memory. A BMC register can be configured to disallow this, and if so, causes an infinite loop in the ast driver which renders the system unusable. Fix this by erroring out if an error is detected. On powerpc systems with EEH, this leads to the device being fenced and the system continuing to operate.
