powerpc/uaccess: fix warning/error with access_ok()
[ Upstream commit 05a4ab823983d9136a460b7b5e0d49ee709a6f86 ]
With the following piece of code, the following compilation warning
is encountered:
if (_IOC_DIR(ioc) != _IOC_NONE) {
int verify = _IOC_DIR(ioc) & _IOC_READ ? VERIFY_WRITE : VERIFY_READ;
if (!access_ok(verify, ioarg, _IOC_SIZE(ioc))) {
drivers/platform/test/dev.c: In function 'my_ioctl':
drivers/platform/test/dev.c:219:7: warning: unused variable 'verify' [-Wunused-variable]
int verify = _IOC_DIR(ioc) & _IOC_READ ? VERIFY_WRITE : VERIFY_READ;
This patch fixes it by referencing 'type' in the macro allthough
doing nothing with it.
