[PATCH v2 15/18] drm/qxl: use qxl_num_crtc directly
qdev->monitors_config->max_allowed is effectively set by the
qxl.num_heads module parameter, stored in the qxl_num_crtc variable.
Lets get rid of the indirection and use the variable qxl_num_crtc
directly. The kernel doesn't need to dereference pointers each time it
needs the value, and when reading the code you don't hav...

[PATCH 6/6] drm/qxl: use qxl_num_crtc directly
Skip the pointless and slightly confusing indirection via
qdev->monitors_config->max_allowed. Just use qxl_num_crtc instead.

[PATCH] drm/qxl: use qxl_num_crtc directly
Just use qxl_num_crtc directly everywhere instead of using
qdev->monitors_config->max_allowed. Drops pointless indirection
and also is less confusing.
