Subject: pinctrl: mark const init data with __initconst instead of __initdata
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=122dbe7e58c7d064a17eefd33205227e6bce85ca;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

pinctrl: mark const init data with __initconst instead of __initdata

As long as there is no other non-const variable marked __initdata in the
same compilation unit it doesn't hurt. If there were one however
compilation would fail with

	error: $variablename causes a section type conflict

because a section containing const variables is marked read only and so
cannot contain non-const variables.
