From 305180bc05019b60ff7aea0b1d68ddbac205ca1f Mon Sep 17 00:00:00 2001 From: Tim Schumacher Date: Tue, 24 Jul 2018 10:46:47 -0700 Subject: Input: iforce - reformat the packet dump output Previously, packets that have been dumped are shown in the kernel log like this: drivers/input/joystick/iforce/iforce-packets.c: info cmd = ff04, data = 56 02 04 00 Use dev_dbg to dump the packages only when requested and to list the parent device as well. Use printf logic to generate the hexdump instead of looping through every char that needs to be printed (which in turn fixes the unnecessary newlines and looks more clean in general). The resulting package dump output does now look like this: usb 2-8: iforce_dump_packet info cmd = ff04, data = 56 02 04 00 Signed-off-by: Tim Schumacher Signed-off-by: Dmitry Torokhov --- drivers/input/joystick/iforce/iforce-ff.c | 4 ++-- drivers/input/joystick/iforce/iforce-main.c | 2 +- drivers/input/joystick/iforce/iforce-packets.c | 10 +++------- drivers/input/joystick/iforce/iforce.h | 2 +- 4 files changed, 7 insertions(+), 11 deletions(-) (limited to 'drivers/input') diff --git a/drivers/input/joystick/iforce/iforce-ff.c b/drivers/input/joystick/iforce/iforce-ff.c index 2ed923874bbc..3536d5f5ad18 100644 --- a/drivers/input/joystick/iforce/iforce-ff.c +++ b/drivers/input/joystick/iforce/iforce-ff.c @@ -52,7 +52,7 @@ static int make_magnitude_modifier(struct iforce* iforce, iforce_send_packet(iforce, FF_CMD_MAGNITUDE, data); - iforce_dump_packet("magnitude: ", FF_CMD_MAGNITUDE, data); + iforce_dump_packet(iforce, "magnitude", FF_CMD_MAGNITUDE, data); return 0; } @@ -174,7 +174,7 @@ static int make_condition_modifier(struct iforce* iforce, data[9] = (100 * lsat) >> 16; iforce_send_packet(iforce, FF_CMD_CONDITION, data); - iforce_dump_packet("condition", FF_CMD_CONDITION, data); + iforce_dump_packet(iforce, "condition", FF_CMD_CONDITION, data); return 0; } diff --git a/drivers/input/joystick/iforce/iforce-main.c b/drivers/input/joystick/iforce/iforce-main.c index 95bbd61d3fbe..f43009703574 100644 --- a/drivers/input/joystick/iforce/iforce-main.c +++ b/drivers/input/joystick/iforce/iforce-main.c @@ -356,7 +356,7 @@ int iforce_init_device(struct iforce *iforce) for (i = 0; c[i]; i++) if (!iforce_get_id_packet(iforce, c + i)) - iforce_dump_packet("info", iforce->ecmd, iforce->edata); + iforce_dump_packet(iforce, "info", iforce->ecmd, iforce->edata); /* * Disable spring, enable force feedback. diff --git a/drivers/input/joystick/iforce/iforce-packets.c b/drivers/input/joystick/iforce/iforce-packets.c index 1cea950276dd..c10169f4554e 100644 --- a/drivers/input/joystick/iforce/iforce-packets.c +++ b/drivers/input/joystick/iforce/iforce-packets.c @@ -29,14 +29,10 @@ static struct { } iforce_hat_to_axis[16] = {{ 0,-1}, { 1,-1}, { 1, 0}, { 1, 1}, { 0, 1}, {-1, 1}, {-1, 0}, {-1,-1}}; -void iforce_dump_packet(char *msg, u16 cmd, unsigned char *data) +void iforce_dump_packet(struct iforce *iforce, char *msg, u16 cmd, unsigned char *data) { - int i; - - printk(KERN_DEBUG __FILE__ ": %s cmd = %04x, data = ", msg, cmd); - for (i = 0; i < LO(cmd); i++) - printk("%02x ", data[i]); - printk("\n"); + dev_dbg(iforce->dev->dev.parent, "%s %s cmd = %04x, data = %*ph\n", + __func__, msg, cmd, LO(cmd), data); } /* diff --git a/drivers/input/joystick/iforce/iforce.h b/drivers/input/joystick/iforce/iforce.h index aee43d14f699..0e9d01f8bcb6 100644 --- a/drivers/input/joystick/iforce/iforce.h +++ b/drivers/input/joystick/iforce/iforce.h @@ -154,7 +154,7 @@ int iforce_init_device(struct iforce *iforce); int iforce_control_playback(struct iforce*, u16 id, unsigned int); void iforce_process_packet(struct iforce *iforce, u16 cmd, unsigned char *data); int iforce_send_packet(struct iforce *iforce, u16 cmd, unsigned char* data); -void iforce_dump_packet(char *msg, u16 cmd, unsigned char *data) ; +void iforce_dump_packet(struct iforce *iforce, char *msg, u16 cmd, unsigned char *data); int iforce_get_id_packet(struct iforce *iforce, char *packet); /* iforce-ff.c */ -- cgit v1.2.3
