Signed-off-by: Daeseok Youn <daeseok.youn@xxxxxxxxx> --- RESEND: This patch was not merged for a long time, if there is any reason why this patch could NOT be merged into staging tree, let me know. There were no comment for this patch. I cannot understand why this patch have to wait long time to merge. And I also sent emails to mailing-lists for reminding this patch... please let me know, what is the problem to merge this patch into staging tree. drivers/staging/dgnc/dgnc_cls.c | 1 - drivers/staging/dgnc/dgnc_driver.h | 1 - drivers/staging/dgnc/dgnc_neo.c | 3 --- 3 files changed, 5 deletions(-) diff --git a/drivers/staging/dgnc/dgnc_cls.c b/drivers/staging/dgnc/dgnc_cls.c index 449a6bb..088b546 100644 --- a/drivers/staging/dgnc/dgnc_cls.c +++ b/drivers/staging/dgnc/dgnc_cls.c @@ -595,7 +595,6 @@ static inline void cls_parse_isr(struct dgnc_board *brd, uint port) /* Transfer data (if any) from Write Queue -> UART. */ spin_lock_irqsave(&ch->ch_lock, flags); ch->ch_flags |= (CH_TX_FIFO_EMPTY | CH_TX_FIFO_LWM); - brd->intr_tx++; ch->ch_intr_tx++; spin_unlock_irqrestore(&ch->ch_lock, flags); cls_copy_data_from_queue_to_uart(ch); diff --git a/drivers/staging/dgnc/dgnc_driver.h b/drivers/staging/dgnc/dgnc_driver.h index 2caeff7..a8d823b 100644 --- a/drivers/staging/dgnc/dgnc_driver.h +++ b/drivers/staging/dgnc/dgnc_driver.h @@ -183,7 +183,6 @@ struct dgnc_board { uint nasync; /* Number of ports on card */ uint irq; /* Interrupt request number */ - ulong intr_tx; /* Count of interrupts */ ulong intr_rx; /* Count of interrupts */ ulong membase; /* Start of base memory of the card */ diff --git a/drivers/staging/dgnc/dgnc_neo.c b/drivers/staging/dgnc/dgnc_neo.c index a3e100b..5f3eacdf 100644 --- a/drivers/staging/dgnc/dgnc_neo.c +++ b/drivers/staging/dgnc/dgnc_neo.c @@ -410,7 +410,6 @@ static inline void neo_parse_isr(struct dgnc_board *brd, uint port) } if (isr & UART_IIR_THRI) { - brd->intr_tx++; ch->ch_intr_tx++; /* Transfer data (if any) from Write Queue -> UART. */ spin_lock_irqsave(&ch->ch_lock, flags); @@ -550,7 +549,6 @@ static inline void neo_parse_lsr(struct dgnc_board *brd, uint port) } if (linestatus & UART_LSR_THRE) { - brd->intr_tx++; ch->ch_intr_tx++; spin_lock_irqsave(&ch->ch_lock, flags); ch->ch_flags |= (CH_TX_FIFO_EMPTY | CH_TX_FIFO_LWM); @@ -559,7 +557,6 @@ static inline void neo_parse_lsr(struct dgnc_board *brd, uint port) /* Transfer data (if any) from Write Queue -> UART. */ neo_copy_data_from_queue_to_uart(ch); } else if (linestatus & UART_17158_TX_AND_FIFO_CLR) { - brd->intr_tx++; ch->ch_intr_tx++; spin_lock_irqsave(&ch->ch_lock, flags); ch->ch_flags |= (CH_TX_FIFO_EMPTY | CH_TX_FIFO_LWM); -- 1.9.1 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
