drivers/audio/wm8904: WM8904 has same problem as that fixed by Juha Niskanen in the MaxTouch driver.

put_reg/get_reg function was overriding i2c transfer error code with i2creset return value, that lead to OK status although actual transfer failed.

progmem_read/write() is incorrectly calculating the target address,
expecting the offset argument is given in a block number. This is
completely wrong and as a result invalid flash region is accessed.
Byte-oriented read/write interfaces of mtd device accept the
target address in a byte offset, not a block number.

drivers/wireless/nrf24l01.c:  Review last PR.  Also got enthused and did major re-work to file to bring it closer to the NuttX coding style.  Fixed a few compile time warnings.
