s390/lcs: Fix null-pointer access in msg

2015-05-18T16:14:18Z

An attempt to configure a CTC device as LCS results in the following error message: (null): Detecting a network adapter for LCS devices failed with rc=-5 (0xfffffffb) "(null)" results from access to &card->dev->dev in lcs_new_device() which is only initialized later in the function. Fix this by using &ccwgdev->dev instead which is initialized before lcs_new_device() is called. Signed-off-by: Peter Oberparleiter Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

s390/net: Delete useless checks before function calls

2015-01-18T04:54:59Z

The function debug_unregister() tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

lcs: replace sscanf by kstrto function

2014-10-27T02:21:39Z

Since a single integer value is read from the supplied buffer use the kstrto functions instead of sscanf. Signed-off-by: Thomas Richter Signed-off-by: Frank Blaschka Signed-off-by: David S. Miller

lcs: replace PTR_RET with PTR_ERR_OR_ZERO

2014-04-28T17:44:09Z

PTR_RET is deprecated. Do not recommend its usage anymore. Use PTR_ERR_OR_ZERO instead. Signed-off-by: Duan Jiong Signed-off-by: Martin Schwidefsky Signed-off-by: Frank Blaschka Signed-off-by: David S. Miller

s390/irq: remove split irq fields from /proc/stat

2013-01-08T09:57:07Z

Now that irq sum accounting for /proc/stat's "intr" line works again we have the oddity that the sum field (first field) contains only the sum of the second (external irqs) and third field (I/O interrupts). The reason for that is that these two fields are already sums of all other fields. So if we would sum up everything we would count every interrupt twice. This is broken since the split interrupt accounting was merged two years ago: 052ff461c8427629aee887ccc27478fc7373237c "[S390] irq: have detailed statistics for interrupt types". To fix this remove the split interrupt fields from /proc/stat's "intr" line again and only have them in /proc/interrupts. This restores the old behaviour, seems to be the only sane fix and mimics a behaviour from other architectures where /proc/interrupts also contains more than /proc/stat's "intr" line does.

lcs: ensure proper ccw setup

2012-09-24T19:45:17Z

Make sure that all ccws used for writing are initialized with zeros - especially since the last ccw contains a TIC for which the unused fields have to be zeros. Signed-off-by: Sebastian Ott Signed-off-by: Frank Blaschka Signed-off-by: David S. Miller
