int ipath_expose_reset

(

struct device *

dev

)

ipath_expose_reset - create a device reset file : the device structure

Only expose a file that lets us reset the device after someone enters diag mode. A device reset is quite likely to crash the machine entirely, so we don't want to normally make it available.

Called with ipath_mutex held.

int ipath_parse_ushort	(	const char *	str,
		unsigned short *	valp
	)

ipath_parse_ushort - parse an unsigned short value in an arbitrary base : the string containing the number : where to put the result

returns the number of bytes consumed, or negative value on error

Definition at line 48 of file ipath_sysfs.c.
