Subject: h8300/uaccess: remove assignment to __gu_val in unhandled case of get_user()
__gu_val is const if the passed ptr is const, giving:
include/linux/pagemap.h: In function 'fault_in_pages_readable':
include/linux/pagemap.h:442:2: error: assignment of read-only variable '__gu_val'
include/linux/pagemap.h:448:4: error: assignment of read-only variable '__gu_val'
include/linux/pagemap.h: In function 'fault_in_multipages_readable':
include/linux/pagemap.h:499:3: error: assignment of read-only variable '__gu_val'
include/linux/pagemap.h:508:3: error: assignment of read-only variable '__gu_val'
make[4]: *** [init/main.o] Error 1
As we don't care about the actual value of __gu_val in the unhandled
case (it will cause a link error anyway), just remove the assignment.
