The following build warning is seen after commit 8bdaa43808 ("regulator:
dbx500: no need to check return value of debugfs_create functions"):

drivers/regulator/dbx500-prcmu.c:144:1: warning: label 'exit_no_debugfs' defined but not used [-Wunused-label]

Remove the unused label and its associated error message.

regulator: dbx500: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

regulator: dbx500-prcmu: Remove unused function dbx500_regulator_testcase()
There isn't any code present within the current kernel to
override this 'weak' function.  Besides returning '0', which
is never checked anyway, the whole function appears to be
superfluous.

Consequently fixes W=1 warning:

 drivers/regulator/dbx500-prcmu.c:113:27: warning: no previous prototype for ‘dbx500_regulator_testcase’ [-Wmissing-prototypes]

Baoyou Xie 5258beedc3 regulator: dbx500: remove unused functions in dbx500-prcmu.c
We get 2 warnings when building kernel with W=1:
drivers/regulator/dbx500-prcmu.c:78:6: warning: no previous prototype for 'ux500_regulator_suspend_debug' [-Wmissing-prototypes]
drivers/regulator/dbx500-prcmu.c:87:6: warning: no previous prototype for 'ux500_regulator_resume_debug' [-Wmissing-prototypes]

In fact, these functions are unused in
dbx500-prcmu.c, but should be removed.

So this patch removes the unused functions.

Joe Perches af78114ec7 regulator: dbx500: Remove use of seq_puts/seq_printf return value
The seq_puts/seq_printf return value, because it's frequently misused,
will eventually be converted to void.

See: commit 1f33c41c03 ("seq_file: Rename seq_overflow() to
     seq_has_overflowed() and make public")

o Remove unnecessary dev_err("seq_<foo> overflow\n") messages

power_state_active_get is used only in this file. Make it static.
While at it also move this function definition inside the
CONFIG_REGULATOR_DEBUG macro as it is called only from within it.
This also avoids further build warning related to unused definition.

Bengt Jonsson 38e968380b regulators/db8500: split off shared dbx500 code
As we progress with DB5500 and future voltage domain regulators
based on very similar hardware as found in the DB8500 PRCMU,
it makes sense to split off the generic parts and introduce
some generic debug code for the DBx500 regulators. This patch
accoplish a basic abstraction of the DBx500 voltage domain
regulators.
