[PATCH 0/2] WM8350 updates

[Mark Brown]

A couple of minor WM8350 updates here.  The first, from Stephen
Rothwell needs to be merged with Linus fairly urgently.  The second
is less urgent since nothing merged should be affected, though it should
still be safe to merge.

[PATCH 1/2] mfd/wm8350: don't export static functions

[Mark Brown]

From: Stephen Rothwell <sfr@canb.auug.org.au>

Today's linux-next build (powerpc allyesconfig) failed like this:

drivers/mfd/wm8350-core.c:1131: error: __ksymtab_wm8350_create_cache causes a section type conflict

Caused by commit 89b4012befb1abca5e86d232bc0e2a797b0d9825 ("mfd: Core
support for the WM8350 AudioPlus PMIC"). wm8350_create_cache is not used
elsewhere, so remove the EXPORT_SYMBOL.

[PATCH 2/2] mfd: Don't store volatile bits in WM8350 register cache

[Mark Brown]

This makes the contents of the cache clearer and fixes incorrect
initialisation of the cache for partially volatile registers.

Both of them merged to my mfd-next tree. I'll send a pull request to Linus
tomorrow.

Thanks for the patches.

Cheers,
Samuel.
