From mboxrd@z Thu Jan 1 00:00:00 1970 From: joshc@codeaurora.org (Josh Cartwright) Date: Tue, 11 Feb 2014 10:23:59 -0600 Subject: [PATCH 1/8] bus: arm-cci: make use of of_find_matching_node_and_match In-Reply-To: <1392135847-30791-1-git-send-email-joshc@codeaurora.org> References: <1392135847-30791-1-git-send-email-joshc@codeaurora.org> Message-ID: <1392135847-30791-2-git-send-email-joshc@codeaurora.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Instead of the of_find_matching_node()/of_match_node() pair, which requires two iterations through the match table, make use of of_find_matching_node_and_match(), which only iterates through the table once. This also has the side effect of fixing the following following error hit during randconfig testing: drivers/bus/arm-cci.c: In function ?cci_probe?: drivers/bus/arm-cci.c:976:49: warning: dereferencing ?void *? pointer [enabled by default] cci_config = of_match_node(arm_cci_matches, np)->data; ^ drivers/bus/arm-cci.c:976:49: error: request for member ?data? in something not a structure or union Signed-off-by: Josh Cartwright --- drivers/bus/arm-cci.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/bus/arm-cci.c b/drivers/bus/arm-cci.c index 962fd35..e249cdb2 100644 --- a/drivers/bus/arm-cci.c +++ b/drivers/bus/arm-cci.c @@ -962,6 +962,7 @@ static const struct of_device_id arm_cci_ctrl_if_matches[] = { static int cci_probe(void) { + const struct of_device_id *match; struct cci_nb_ports const *cci_config; int ret, i, nb_ace = 0, nb_ace_lite = 0; struct device_node *np, *cp; @@ -969,11 +970,11 @@ static int cci_probe(void) const char *match_str; bool is_ace; - np = of_find_matching_node(NULL, arm_cci_matches); + np = of_find_matching_node_and_match(NULL, arm_cci_matches, &match); if (!np) return -ENODEV; - cci_config = of_match_node(arm_cci_matches, np)->data; + cci_config = match->data; if (!cci_config) return -ENODEV; -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation
