From 4fee7e168ba08ed067ee9aafe4a0a19387117be4 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Tue, 6 Mar 2012 20:43:45 +0100 Subject: [PATCH] staging:iio: Fix compile error without CONFIG_DEBUG_FS commit e553f182d ("staging: iio: core: Introduce debugfs support, add support for direct register access") added a '#if defined(CONFIG_DEBUG_FS)' around iio_read_channel_ext_info and iio_write_channel_ext_info causing the following compile error if CONFIG_DEBUG_FS is not defined. drivers/staging/iio/industrialio-core.c:621:11: error: 'iio_read_channel_ext_info' undeclared (first use in this function) drivers/staging/iio/industrialio-core.c:623:11: error: 'iio_write_channel_ext_info' undeclared (first use in this function) This patch fixes the issue by moving the functions out of the '#if defined(CONFIG_DEBUG_FS)' section again.
