Subject: [rt2x00-users] [PATCH 1/5] rt2x00: add rt2x00_has_cap_*
helpers
Message-ID: <[email protected]>
The rt2x00 code directly accesses the 'cap_flags'
field of 'struct rt2x00_dev' when checking presence
of a given capability flag. The direct access needs
long expressions which lowers readability of the code.
Add a few helper functions which can be used to test
device capabilities without directly accessing the
cap_flags filed.
