From 5aad724280b9f8ffff3a55311ef0ba35ebb4099a Mon Sep 17 00:00:00 2001 From: Jarod Wilson Date: Thu, 6 Jan 2011 16:59:36 -0300 Subject: [media] rc: fix up and genericize some time unit conversions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The ene_ir driver was using a private define of MS_TO_NS, which is meant to be microseconds to nanoseconds. The mceusb driver copied it, intending to use is a milliseconds to microseconds. Lets move the defines to a common location, expand and standardize them a touch, so that we now have: MS_TO_NS - milliseconds to nanoseconds MS_TO_US - milliseconds to microseconds US_TO_NS - microseconds to nanoseconds Reported-by: David Härdeman CC: Maxim Levitsky Signed-off-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab --- drivers/media/rc/mceusb.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'drivers/media/rc/mceusb.c') diff --git a/drivers/media/rc/mceusb.c b/drivers/media/rc/mceusb.c index 0fef6ef..2d91134 100644 --- a/drivers/media/rc/mceusb.c +++ b/drivers/media/rc/mceusb.c @@ -48,7 +48,6 @@ #define USB_BUFLEN 32 /* USB reception buffer length */ #define USB_CTRL_MSG_SZ 2 /* Size of usb ctrl msg on gen1 hw */ #define MCE_G1_INIT_MSGS 40 /* Init messages on gen1 hw to throw out */ -#define MS_TO_NS(msec) ((msec) * 1000) /* MCE constants */ #define MCE_CMDBUF_SIZE 384 /* MCE Command buffer length */ @@ -817,7 +816,7 @@ static void mceusb_handle_command(struct mceusb_dev *ir, int index) switch (ir->buf_in[index]) { /* 2-byte return value commands */ case MCE_CMD_S_TIMEOUT: - ir->rc->timeout = MS_TO_NS((hi << 8 | lo) / 2); + ir->rc->timeout = MS_TO_US((hi << 8 | lo) / 2); break; /* 1-byte return value commands */ @@ -858,7 +857,7 @@ static void mceusb_process_ir_data(struct mceusb_dev *ir, int buf_len) ir->rem--; rawir.pulse = ((ir->buf_in[i] & MCE_PULSE_BIT) != 0); rawir.duration = (ir->buf_in[i] & MCE_PULSE_MASK) - * MS_TO_NS(MCE_TIME_UNIT); + * MS_TO_US(MCE_TIME_UNIT); dev_dbg(ir->dev, "Storing %s with duration %d\n", rawir.pulse ?
