regmap: Fix debugfs-file 'registers' mode
The macro "REGMAP_ALLOW_WRITE_DEBUGFS" can be used to enable write support on the registers file in the debugfs. The mode of the file is fixed to 0400 so it is not possible to write the file ever. This patch fixes the mode by setting it to the correct value depending on the macro. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@kernel.org>
