| |
2.6.34-stable review patch. If anyone has any objections, please let us know.
------------------
From: Sergei Shtylyov <sshtylyov@ru.mvista.com>
commit 9297688a9257d73956d4bba484d9dd331ca72c25 upstream.
Attempt to build MUSB driver with CONFIG_PM=y (e.g. in the OTG mode) on DaVinci results in these link errors:
drivers/built-in.o: In function `musb_restore_context': led-triggers.c:(.text+0x714d8): undefined reference to `musb_platform_restore_context' drivers/built-in.o: In function `musb_save_context': led-triggers.c:(.text+0x71788): undefined reference to `musb_platform_save_context'
This turned out to be caused by commit 9957dd97ec5e98dd334f87ade1d9a0b24d1f86eb (usb: musb: Fix compile error for omaps for musb_hdrc). Revert it, taking into account the rename of CONFIG_ARCH_OMAP34XX into CONFIG_ARCH_OMAP3 (which that commit fixed in a completely inappropriate way) and the recent addition of OMAP4 support.
