[PATCH] gpu: drm: nouveau: nvkm: nv40: Replace mdelay() with msleep() in nv40_sensor_setup()
nv40_sensor_setup() is never called in atomic context.
It calls mdelay() to busily wait, which is not necessary.
mdelay() can be replaced with msleep().
This is found by a static analysis tool named DCNS written by myself
