#     powerpc: Remove 'type' argument from access_ok() function
#     
#     In commit 05a4ab823983 ("powerpc/uaccess: fix warning/error with
#     access_ok()") an attempt was made to remove a warning by referencing
#     the variable `type`, however in commit 96d4f267e40f ("Remove 'type'
#     argument from access_ok() function") the variable `type` has been
#     removed.
#     
#     Revert commit 05a4ab823983 ("powerpc/uaccess: fix warning/error with
#     access_ok()") to fix the following compilation error:
#     
#       arch/powerpc/include/asm/uaccess.h:66:32: error: ‘type’ undeclared (first use in this function)
#     
#     Fixes: 96d4f267e40f ("Remove 'type' argument from access_ok() function")
