1.7.9.5

The dma_alloc_coherent return an "void *" not an "void __iomen *". It uses the wrong parameters when calls dma_free coherent function, and "DEVICE_ATTR_RO" should be defined as static.

The sparse tool output logs as the following:

There is an unnecessary space at the front of the code.

The smatch tool output logs as the following:
of_coresight.c:89 of_coresight_alloc_memory() warn:
inconsistent indenting
