Remove redundant irqchip_init() callback. The default case of NULL will result in invoking irqchip_init() anyway. Signed-off-by: Magnus Damm <damm@opensource.se> [ horms+renesas@verge.net.au: Trimmed patch to remove portion that updates the r8a73a4 SoC and altered the subject to use the same format as the patch that updates the r8a73a4. ] Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
