Did you consider reusing the group flags, e.g., parser->groups |= (1
<< HID_GROUP_MULTITOUCH)? This change could be made regardless of the
parser logic.
If nobody is against changing the values of the different groups across
kernel version (which should be harmless), then I fully agree, we can
use the group item as a bit field (but we would be able to only have 16
different device groups).
Hmm, that might become a problem. E.g. all the HID sensors might be used
stand alone (without a sensor-hub, if someone modifies the drivers). But
I agree that currently the flags are just confusing and would introduce
them only if the number of groups reaches the limit.
- hid->group = HID_GROUP_GENERIC;
+ parser = vzalloc(sizeof(struct hid_parser));
Argh, I realize it is inevitable for this patch, but it still makes my
eyes bleed. The parser takes quite a bit of memory...
Yep, my first attempt was to remove it, then I re-added it with a small
tear...
So you actually create a new parser and the subject (that existing) of
this patch is misleading.
