kstrtoint() returns "0 on success, -ERANGE on overflow and -EINVAL on parsing error". In contrast, manager_sysfs_remove_store() and manager_sysfs_dump_store() checked for 1 which always failed the operation. I fixed this.

Fixes: f9a21a3f4919 ("staging: greybus: audio_manager_sysfs: Replace sscanf with kstrto* to single variable conversion.") Signed-off-by: Alexander A. Klimov grandmaster@al2klimov.de --- v2: style (X,!X instead of X!=0,X==0)
