5 MIME-Version: 1.0
6 Content-Type: text/plain; charset=UTF-8
7 Content-Transfer-Encoding: 8bit
8
9 FREQ is a ridiculously short name for a platform-specific macro in a
10 generic header, and it now conflicts with an enumeration in the
11 gspca/ov519 driver.
12
13 Also delete conditional reference to ixp4xx_get_board_tick_rate()
14 which is not defined anywhere.
