[PATCH] x86/PVH: avoid 32-bit build warning when obtaining VGA console info
Posted by Jan Beulich 1 year ago
In the commit referenced below I failed to pay attention to this code
also being buildable as 32-bit. Adjust the type of "ret" - there's no
real need for it to be wider than 32 bits.

Fixes: 934ef33ee75c ("x86/PVH: obtain VGA console info in Dom0")
Reported-by: kernel test robot <lkp@intel.com>
