mfd da903x: section fix

From: David Brownell <[email protected]>

This fixes the following section warning:

WARNING: vmlinux.o(.devinit.text+0x3d36): Section mismatch in reference from the function da903x_add_subdevs() to the function .devexit.text:da903x_remove_subdevs() The function __devinit da903x_add_subdevs() references
a function __devexit da903x_remove_subdevs().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __devexit annotation of da903x_remove_subdevs() so it may be used outside an exit section.

It might be nice to have an "init and exit" section annotation for such cases; in this case the waste is only about 40 bytes (x86 test build).

Indeed.

Samuel, please consider merge, thanks.
