Linville" , Vladimir Kondratiev , ath10k@lists.infradead.org, linux-wireless@vger.kernel.org, netdev@vger.kernel.org, linux-kernel@vger.kernel.org, wil6210 Date: Mon, 22 Sep 2014 10:35:34 -0700 Content-Type: text/plain; charset="ISO-8859-1" Mime-Version: 1.0 Sender: linux-wireless-owner@vger.kernel.org List-ID: The return values are not used by callers of these functions so change the functions to return void. Other miscellanea: o add __printf verification to wil6210 logging functions No format/argument mismatches found Signed-off-by: Joe Perches --- This change is associated to a desire to eventually change printk to return void. drivers/net/wireless/ath/ath10k/debug.c | 18 +++++------------- drivers/net/wireless/ath/ath10k/debug.h | 6 +++--- drivers/net/wireless/ath/ath6kl/common.h | 2 +- drivers/net/wireless/ath/ath6kl/debug.c | 28 ++++++++-------------------- drivers/net/wireless/ath/ath6kl/debug.h | 13 ++++++------- drivers/net/wireless/ath/wil6210/debug.c | 14 ++++---------- drivers/net/wireless/ath/wil6210/wil6210.h | 7 +++++-- 7 files changed, 32 insertions(+), 56 deletions(-) diff --git a/drivers/net/wireless/ath/ath10k/debug.c b/drivers/net/wireless/ath/ath10k/debug.c index f3f0a80..29eb2aa 100644 --- a/drivers/net/wireless/ath/ath10k/debug.c +++ b/drivers/net/wireless/ath/ath10k/debug.c @@ -106,21 +106,18 @@ struct ath10k_dump_file_data { u8 data[0];
