To: linux-arm-kernel; +Cc: linux-kernel, Suzuki K Poulose, Mathieu Poirier
Each coresight device prepares a description for coresight_register()
in struct coresight_desc. Once we register the device, the description is
useless and can be freed. The coresight_desc is small enough (48bytes on 64bit)
to be allocated on the stack. Hence use an automatic variable to avoid a
needless dynamic allocation and wasting the memory(which will only be free'd
when the device is destroyed).
