fs/compat_rw_copy_check_uvector: add missing compat_ptr call
A call to access_ok is missing a compat_ptr conversion. Introduced with
b83733639a494d5f42fa00a2506563fbd2d3015d "compat: factor out
compat_rw_copy_check_uvector from compat_do_readv_writev"
fs/compat.c: In function 'compat_rw_copy_check_uvector':
fs/compat.c:629: warning: passing argument 1 of '__access_ok' makes pointer from integer without a cast
