static analysis bug report: ALSA: swapped client and port arguments in calls to snd_seq_oss_fill_addr

[Colin Ian King]

Hi there,

Static analysis with Coverity has picked up two potential issues with
the call to function snd_seq_oss_fill_addr. The prototype of
snd_seq_oss_fill_addr is as follows:

static inline void
snd_seq_oss_fill_addr(struct seq_oss_devinfo *dp, struct snd_seq_event
*ev,int dest_client, int dest_port)


However, in sound/core/seq/oss/seq_oss_ioctl.c in function
snd_seq_oss_oob_user it is being called as follows:

	 snd_seq_oss_fill_addr(dp, &tmpev, dp->addr.port, dp->addr.client);

and also in sound/core/seq/oss/seq_oss_rw.c in function is it also being
called as follows:

	snd_seq_oss_fill_addr(dp, &event, dp->addr.port, dp->addr.client);

..as one can see, in both cases the port and client arguments are
swapped compared to the function prototype.  I doubt this is intentional
but you never know. Are these bugs?
