[PATCH 1/9] Remove unused headers <linux/jz4740-adc.h> and <linux/power/jz4740-battery.h>

[PATCH 1/9] Remove unused headers <linux/jz4740-adc.h> and <linux/power/jz4740-battery.h>

[Jonathan Corbet]

Commit ff71266aa490 ("mfd: Drop obsolete JZ4740 driver") removed the last
file to include <linux/jz4740-adc.h> but left the header file itself
behind.  Nothing uses it, remove it now.

Similarly, aea12071d6fc ("power/supply: Drop obsolete JZ4740 driver")
deleted the last use of <linux/power/jz4740-battery.h>, so remove that one
too.

It appears as though there are still references to both of these
*devices* in the kernel tree.  Should those be removed also?

Patch looks fine though.

Let me know if you want me to take it in via MFD.  Otherwise:

These files were for older drivers that were since then replaced by 
newer drivers; JZ47xx SoCs are still officially supported and 
maintained.

You can take it through MFD, no immutable branch needed.

Okay, no problem.

Since the merge-window is already open, we'll aim for v5.17.
