From: Felipe Balbi <felipe.ba...@nokia.com> Date: Thu, 4 Mar 2010 09:45:53 +0200 Subject: [PATCH] arm: omap: ehci: avoid compiler error with touchbook the early_param() call in board-omap3touchbook.c expands to: static const char __setup_str_early_touchbook_revision[] __section(.init.rodata) _aligned(1) = tbr; [...] and we have a non-const variable being added to the same section: static struct ehci_hcd_omap_platform_data ehci_pdata __section(.init.rodata); because of that, gcc generates a section type conflict which can (and actually should) be avoided by marking const every variable marked with __initconst. This patch fixes that for the ehci_hdc_omap_platform_data.
