Subject: [PATCH 3.16 010/134] pinctrl: sh-pfc: Update info pointer after
 SoC-specific init

3.16.47-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Geert Uytterhoeven <geert+renesas@...der.be>

commit 3091ae775fae17084013021d01513bc1ad274e6a upstream.

Update the sh_pfc_soc_info pointer after calling the SoC-specific
initialization function, as it may have been updated to e.g. handle
different SoC revisions.  This makes sure the correct subdriver name is
printed later.

Fixes: 0c151062f32c9db8 ("sh-pfc: Add support for SoC-specific initialization")
