Cc: Amit Shah Subject: [Qemu-devel] [PATCH 1/3] char: check for initial_reset_issued unnecessary X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: qemu-devel.nongnu.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org At init, qemu_chr_reset is always called with initial_reset_issued set to 1. So checking for it to be set is not necessary. A later patch will make use of initial_reset_issued to send the reset event only if the char device is opened instead of each time when qemu resets it Signed-off-by: Amit Shah --- qemu-char.c | 5 ++--- 1 files changed, 2 insertions(+), 3 deletions(-) diff --git a/qemu-char.c b/qemu-char.c index 8084a67..99ab471 100644 --- a/qemu-char.c +++ b/qemu-char.c @@ -127,7 +127,7 @@ static void qemu_chr_reset_bh(void *opaque) void qemu_chr_reset(CharDriverState *s) { - if (s->bh == NULL && initial_reset_issued) { + if (s->bh == NULL) { s->bh = qemu_bh_new(qemu_chr_reset_bh, s); qemu_bh_schedule(s->bh); } @@ -137,11 +137,10 @@ void qemu_chr_initial_reset(void) { CharDriverState *chr; - initial_reset_issued = 1; - QTAILQ_FOREACH(chr, &chardevs, next) { qemu_chr_reset(chr); } + initial_reset_issued = 1; } int qemu_chr_write(CharDriverState *s, const uint8_t *buf, int len)
