4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Ellerman <mpe@xxxxxxxxxxxxxx>
commit 609d5a1b2b35bb62b4b3750396e55453160c2a17 upstream.
Since commit ea8daa7b9784 ("kbuild: Add option to turn incompatible
pointer check into error"), assignments from an incompatible pointer
types have become a hard error, eg:
drivers/i2c/busses/i2c-cpm.c:545:91: error: passing argument 3 of
'dma_alloc_coherent' from incompatible pointer type
Fix the build break by converting txdma & rxdma to dma_addr_t.
