Subject: [PATCH] staging : android : fix checkpatch issues

drivers/staging/android/
ion/ion.c :
 - WARNNING: Unnecessary space after function pointer name
 - ERROR: return is not a function, parentheses are not required
 - WARNNING: Prefer seq_puts to seq_printf
 - WARNING: quoted string split across lines

ion/ion_priv.h :
 - WARNING: Unnecessary space after function pointer name

sync.h :
 - WARNING: missing space after return type

timed_output.h :
 - WARNING: Multiple spaces after return type
