Subject: [PATCH 1/2] mtd: rawnand: use unnamed union in struct nand_op_instr
Getting the instruction private data ends up with a quite long
accessors, annoyingly.
Use anonymous union field to save 4 characters "ctx." This should
not introduce ambiguity.
I do not know when GCC started to support unnamed struct/union field,
but at least, the current minimum compiler version, GCC 4.6 supports
it, and so does Clang.
The unnamed struct/union was standardized only recently (ISO C11).
Anyway, the kernel code relies on the GNU extension to some extent.
Besides, struct nand_flash_dev in the same header exploits it.
If this is a problem, somebody should already have reported it.
