Subject: Re: [PATCH v7 00/48] atmel_mxt_ts misc
Hello Dmitry
I have submitted v8 patch-set to address your comments towards v7 patch-set,
most of checkpatch warnings and errors have been addressed,
But I didn't update for following two types of warnings
since I want to keep consistency with legacy code
WARNING: DEVICE_ATTR unusual permissions '0600' used
#290: FILE: drivers/input/touchscreen/atmel_mxt_ts.c:3761:
+static DEVICE_ATTR(debug_v2_enable, 0600, NULL,
WARNING: Consider renaming function(s) 'mxt_debug_notify_show' to
'debug_notify_show'
#292: FILE: drivers/input/touchscreen/atmel_mxt_ts.c:3763:
+static DEVICE_ATTR(debug_notify, 0444, mxt_debug_notify_show, NULL);
please let me know if you have different view on this
Thanks,
Jiada
