Subject: Re: [PATCH 35/36] hid: roccat: convert class code to use bin_attrs
 in groups

Hello Greg,
looking through the patch I found the following:

In hid-roccat-kone.c, PROFILE_ATTR macro:
The line
 .private = &profile_numbers[number],
should read
 .private = &profile_numbers[number-1],

Regarding the compiler warning about unused pyra_sysfs_write_settings:
The attribute is indeed readwrite, but the code to write is not standard
code. The read function was created with the PYRA_SYSFS_R macro and the
write function was written manually. Used were both by
PYRA_BIN_ATTRIBUTE_RW.
In this case I would keep the PYRA_SYSFS_* macros standalone so that the
calling code looks like this:

PYRA_SYSFS_W(control, CONTROL);
PYRA_SYSFS_RW(info, INFO);
PYRA_SYSFS_RW(profile_settings, PROFILE_SETTINGS);
PYRA_SYSFS_RW(profile_buttons, PROFILE_BUTTONS);
PYRA_SYSFS_R(settings, SETTINGS);

PYRA_BIN_ATTRIBUTE_W(control, CONTROL);
PYRA_BIN_ATTRIBUTE_RW(info, INFO);
PYRA_BIN_ATTRIBUTE_RW(profile_settings, PROFILE_SETTINGS);
PYRA_BIN_ATTRIBUTE_RW(profile_buttons, PROFILE_BUTTONS);
PYRA_BIN_ATTRIBUTE_RW(settings, SETTINGS);

Another thing: Why does nobody (besides me) use the get_maintainer.pl
script, so I have to search manually for patches regarding my code?

Have a nice day,
Stefan
