Everybody agrees with standardizing things but the problem is, the
standardization will only happen when more than one person implements the
same functionality.
The primary discussion is around the usage of chardev nodes for WLAN but
we made it clear that WLAN doesn't need this chardev node for working at
all. I agree that the commit message is a bit misleading and I hope that
Hemant will fix it in next revision.
