From: Uwe Hermann Date: Tue, 11 Jun 2013 16:55:47 +0000 (+0200) Subject: scanalogic2: Shorten a few function name prefixes. X-Git-Tag: libsigrok-0.2.1~69 X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=79914b3a62adb1b0b054d23c2721ce80eb7ba9ea;p=libsigrok.git scanalogic2: Shorten a few function name prefixes. The driver-private helper functions in protocol.c can have a shorter prefix to make the code look nicer. --- diff --git a/hardware/ikalogic-scanalogic2/api.c b/hardware/ikalogic-scanalogic2/api.c index a9bb456f..501a58fe 100644 --- a/hardware/ikalogic-scanalogic2/api.c +++ b/hardware/ikalogic-scanalogic2/api.c @@ -27,7 +27,7 @@ static const int hwcaps[] = { SR_CONF_CAPTURE_RATIO, };
