Thomas Gleixner a9446a906f lib/vdso/32: Remove inconsistent NULL pointer checks ... The 32bit variants of vdso_clock_gettime()/getres() have a NULL pointer check for the timespec pointer. That's inconsistent vs. 64bit. But the vdso implementation will never be consistent versus the syscall because the only case which it can handle is NULL. Any other invalid pointer will cause a segfault. So special casing NULL is not really useful. Remove it along with the superflouos syscall fallback invocation as that will return -EFAULT anyway. That also gets rid of the dubious typecast which only works because the pointer is NULL.
