From 32fb1939e3921691c71f7cd274d80d487af72fae Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Mon, 12 Oct 2015 23:22:39 +0200 Subject: usb/host/fotg210: Add function: output_buf_tds_dir() checkpatch complains about too many leading tabs because the switch statement starts after 6 tabs. fill_periodic_buffer() -> for() -> do -> switch() -> if() -> list_for_each_entry() and finally the last switch(). This patch moves the list_for_each_entry() and the last switch() to a new function named output_buf_tds_dir(). This change makes the code easier to read and calm down checkpatch. This patch changes it to: fill_periodic_buffer() -> for() -> do -> switch() -> if() -> output_buf_tds_dir() Signed-off-by: Peter Senna Tschudin Signed-off-by: Greg Kroah-Hartman --- drivers/usb/host/fotg210-hcd.c | 62 +++++++++++++++++++++--------------------- 1 file changed, 31 insertions(+), 31 deletions(-) (limited to 'drivers/usb') diff --git a/drivers/usb/host/fotg210-hcd.c b/drivers/usb/host/fotg210-hcd.c index 158423230a88..eb825c5ab327 100644 --- a/drivers/usb/host/fotg210-hcd.c +++ b/drivers/usb/host/fotg210-hcd.c @@ -493,6 +493,34 @@ static ssize_t fill_async_buffer(struct debug_buffer *buf) return strlen(buf->output_buf); } +/* count tds, get ep direction */ +static unsigned output_buf_tds_dir(char *buf, struct fotg210_hcd *fotg210, + struct fotg210_qh_hw *hw, struct fotg210_qh *qh, unsigned size) +{ + u32 scratch = hc32_to_cpup(fotg210, &hw->hw_info1); + struct fotg210_qtd *qtd; + char *type = ""; + unsigned temp = 0; + + /* count tds, get ep direction */ + list_for_each_entry(qtd, &qh->qtd_list, qtd_list) { + temp++; + switch ((hc32_to_cpu(fotg210, qtd->hw_token) >> 8) & 0x03) { + case 0: + type = "out"; + continue; + case 1: + type = "in"; + continue; + } + } + + return scnprintf(buf, size, "(%c%d ep%d%s [%d/%d] q%d p%d)", + speed_char(scratch), scratch & 0x007f, + (scratch >> 8) & 0x000f, type, qh->usecs, + qh->c_usecs, temp, (scratch >> 16) & 0x7ff); +} + #define DBG_SCHED_LIMIT 64 static ssize_t fill_periodic_buffer(struct debug_buffer *buf) { @@ -564,37 +592,9 @@ static ssize_t fill_periodic_buffer(struct debug_buffer *buf) } /* show more info the first time around */ if (temp == seen_count) { - u32 scratch = hc32_to_cpup(fotg210, - &hw->hw_info1); - struct fotg210_qtd *qtd; - char *type = ""; - - /* count tds, get ep direction */ - temp = 0; - list_for_each_entry(qtd, - &p.qh->qtd_list, - qtd_list) { - temp++; - switch (0x03 & (hc32_to_cpu( - fotg210, - qtd->hw_token) >> 8)) { - case 0: - type = "out"; - continue; - case 1: - type = "in"; - continue; - } - } - - temp = scnprintf(next, size, - "(%c%d ep%d%s [%d/%d] q%d p%d)", - speed_char(scratch), - scratch & 0x007f, - (scratch >> 8) & 0x000f, type, - p.qh->usecs, p.qh->c_usecs, - temp, - 0x7ff & (scratch >> 16)); + temp = output_buf_tds_dir(next, + fotg210, hw, + p.qh, size); if (seen_count < DBG_SCHED_LIMIT) seen[seen_count++].qh = p.qh; -- cgit v1.2.3
