[PATCH] mach-s3c64xx:Fix error handling for certain calls to s3c_gpio_cfgpin_range in the file dev-audio.c

[xerofoify@gmail.com (Nicholas Krause)]

This fixes error handling for calls to the function
s3c_gpio_cfgpin_range in the file dev-audio.c that
assume calls to this particular function always run
successfully to properly check now if these calls
fail by returning a error code and if so return it
directly to the call of these functions in order for
the caller to be able to handle these failed calls in
its own error path(s).
