In the au1550nd driver we have 2 implementations of read_buf. The previously mentioned commit modified the au_read_buf() implementation to match the function pointer, but not au_read_buf16(). This results in a compiler warning for MIPS db1xxx_defconfig builds: drivers/mtd/nand/raw/au1550nd.c:443:57: warning: pointer type mismatch in conditional expression Fix this by updating the prototype of au_read_buf16() to take a struct nand_chip pointer as its first argument, as is expected after commit 7e534323c416 ("mtd: rawnand: Pass a nand_chip object to chip->read_xxx() hooks"). Note that this shouldn't have caused any functional issues at runtime, since the offset of the struct mtd_info within struct nand_chip is 0 making mtd_to_nand() effectively a type-cast.

And platform specific changes: - Major improvements to Ingenic SoC support from Paul Cercueil, mostly enabled by the inclusion of the new TCU (timer-counter unit) drivers he's spent a very patient year or so working on.
