From 97607d157c133ab18dfcd77fa836e37fa950a44a Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 29 Nov 2011 12:52:39 +0100 Subject: pinctrl: make a copy of pinmux map This makes a deep copy of the pinmux function map instead of keeping the copy supplied from the platform around. This makes it possible to tag the platforms map with __initdata as is also done as part of this patch. Rationale: a certain target platform (PXA) has numerous pinmux maps, many of which will be lying around unused after boot in a multi-platform binary. Instead, deep-copy the one we're going to use and tag them all __initdata so they go away after boot. ChangeLog v1->v2: - Fixup the deep copy, missed a few items on the struct, plus mark bool member non-const since we're making runtime copies if this stuff now. ChangeLog v2->v3: - Make a shallow copy (just copy the array of map structs) as Arnd noticed, string constants never get discarded by the kernel anyway, so these pointers may be safely copied over.
