[PATCH v2 11/15] gpio/samsung: mark const init data with __initconst instead of __initdata

From: Uwe Kleine-KÃnig
Date: Fri Mar 30 2012 - 16:06:47 EST


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.
