[PATCH 11/11] drm/vmwgfx: Use preprocessor macro for FIFO allocation

Deepak Singh Rawat drawat at vmware.com
Fri Apr 5 18:40:51 UTC 2019


Whenever FIFO allocation fails an error message is printed to dmesg.
Since this is common operation a lot of similar messages are scattered
everywhere. Use preprocessor macro to remove this cluttering.
