2016-03-14phy: fixed: Fix removal of phys.Andrew Lunn
The fixed phys delete function simply removed the fixed phy from the internal linked list and freed the memory. It however did not unregister the associated phy device. This meant it was still possible to find the phy device on the mdio bus. Make fixed_phy_del() an internal function and add a fixed_phy_unregister() to unregisters the phy device and then uses fixed_phy_del() to free resources. Modify DSA to use this new API function, so we don't leak phys. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-03-14tcp: Add RFC4898 tcpEStatsPerfDataSegsOut/InMartin KaFai Lau
Per RFC4898, they count segments sent/received containing a positive length data segment (that includes retransmission segments carrying data). Unlike tcpi_segs_out/in, tcpi_data_segs_out/in excludes segments carrying no data (e.g. pure ack). The patch also updates the segs_in in tcp_fastopen_add_skb() so that segs_in >= data_segs_in property is kept. Together with retransmission data, tcpi_data_segs_out gives a better signal on the rxmit rate. v6: Rebase on the latest net-next v5: Eric pointed out that checking skb->len is still needed in tcp_fastopen_add_skb() because skb can carry a FIN without data. Hence, instead of open coding segs_in and data_segs_in, tcp_segs_in() helper is used. Comment is added to the fastopen case to explain why segs_in has to be reset and tcp_segs_in() has to be called before __skb_pull(). v4: Add comment to the changes in tcp_fastopen_add_skb() and also add remark on this case in the commit message. v3: Add const modifier to the skb parameter in tcp_segs_in() v2: Rework based on recent fix by Eric: commit a9d99ce28ed3 ("tcp: fix tcpi_segs_in after connection establishment") Signed-off-by: Martin KaFai Lau <kafai@fb.com> Cc: Chris Rapier <rapier@psc.edu> Cc: Eric Dumazet <edumazet@google.com> Cc: Marcelo Ricardo Leitner <mleitner@redhat.com> Cc: Neal Cardwell <ncardwell@google.com> Cc: Yuchung Cheng <ycheng@google.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2016-03-14rtc: Add functions to set and read rtc offsetJoshua Clayton
A number of rtc devices, such as the NXP pcf2123 include a facility to adjust the clock in order to compensate for temperature or a crystal, capacitor, etc, that results in the rtc clock not running at exactly 32.768 kHz. Data sheets I have seen refer to this as a clock offset, and measure it in parts per million, however they often reference ppm to 2 digits of precision, which makes integer ppm less than ideal. We use parts per billion, which more than covers the precision needed and works nicely within 32 bits Signed-off-by: Joshua Clayton <stillcompiling@gmail.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
2016-03-14rtc: max77686: move initialisation of rtc regmap, irq chip locallyLaxman Dewangan
To make RTC block of MAX77686/MAX77802 as independent driver, move the registration of i2c device, regmap for register access and irq_chip for interrupt support inside the RTC driver. Removed the same initialisation from MFD driver. Having this change will allow to reuse this driver for different PMIC/devices from Maxim Semiconductor if they kept same RTC IP on different PMIC. Some of examples as PMIC MAX77620, MAX20024 where same RTC IP used and hence driver for these chips will use this driver only for RTC support.

2016-03-14leds: core: avoid error message when a USB LED device is unpluggedHeiner Kallweit
When a USB LED device is unplugged the remove call chain calls led_classdev_unregister which tries to switch the LED off. As the device has been removed already this results in a ENODEV error message in dmesg. Avoid this error message by ignoring ENODEV in calls from led_classdev_unregister if the LED device is flagged as pluggable. Therefore a new flag LED_HW_PLUGGABLE was introduced which should be set by all LED drivers handling pluggable LED devices (mainly USB LED devices).
