[PATCH] staging: vc04_services: Fix NULL ptr sparse warnings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In calls to queue_message() in vchiq_core.c, the "void *context"
parameter is set as 0 rather than NULL. This patch amends each call to
use the proper NULL pointer. The following sparse warnings are fixed:

drivers/staging/vc04_services/interface/vchiq_arm/vchiq_core.c:1623:23: warning: Using plain integer as NULL pointer
