Ben Dooks d0e5ab9e63 riscv: uaccess: fix type of 0 variable on error in get_user() ... commit b9b916aee6 upstream. If the get_user(x, ptr) has x as a pointer, then the setting of (x) = 0 is going to produce the following sparse warning, so fix this by forcing the type of 'x' when access_ok() fails. fs/aio.c:2073:21: warning: Using plain integer as NULL pointer Signed-off-by: Ben Dooks <ben-linux@fluff.org> Reviewed-by: Palmer Dabbelt <palmer@rivosinc.com> Link: https://lore.kernel.org/r/20221229170545.718264-1-ben-linux@fluff.org Cc: stable@vger.kernel.org Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2023-01-18 11:30:50 +01:00
