Bug Description

Building this package against the unstable kernel with clang I hit the following build failure:

<DKMSDIR>>/build/nvidia/390.132/build/common/inc/nv-linux.h: In function ‘nv_ioremap_nocache’:
<<DKMSDIR>>/build/nvidia/390.132/build/common/inc/nv-linux.h:556:17: error: implicit declaration of function ‘ioremap_nocache’; did you mean ‘ioremap_cache’? [-Werror=implicit-function-declaration]
  556 | void *ptr = ioremap_nocache(phys, size);
      | ^~~~~~~~~~~~~~~
      | ioremap_cache

Building the same dkms package with gcc this works fine. I think clang is being more pedantic about the missing declaration for ioremap_nocache()
