2016-06-23can: fix oops caused by wrong rtnl dellink usageOliver Hartkopp
For 'real' hardware CAN devices the netlink interface is used to set CAN specific communication parameters. Real CAN hardware can not be created nor removed with the ip tool ... This patch adds a private dellink function for the CAN device driver interface that does just nothing. It's a follow up to commit 993e6f2fd ("can: fix oops caused by wrong rtnl newlink usage") but for dellink.

2016-06-23can: fix handling of unmodifiable configuration options fixOliver Hartkopp
With upstream commit bb208f144cf3f59 (can: fix handling of unmodifiable configuration options) a new can_validate() function was introduced. When invoking 'ip link set can0 type can' without any configuration data can_validate() tries to validate the content without taking into account that there's totally no content. This patch adds a check for missing content.

2016-06-23ubi: Make recover_peb power cut awareRichard Weinberger
recover_peb() was never power cut aware, if a power cut happened right after writing the VID header upon next attach UBI would blindly use the new partial written PEB and all data from the old PEB is lost. In order to make recover_peb() power cut aware, write the new VID with a proper crc and copy_flag set such that the UBI attach process will detect whether the new PEB is completely written or not. We cannot directly use ubi_eba_atomic_leb_change() since we'd have to unlock the LEB which is facing a write error.

2016-06-23gpio: make library immune to error pointersLinus Walleij

2016-06-23gpio: make sure gpiod_to_irq() returns negative on NULL descLinus Walleij
commit 54d77198fdfbc4f0fe11b4252c1d9c97d51a3264 ("gpio: bail out silently on NULL descriptors") doesn't work for gpiod_to_irq(): drivers assume that NULL descriptors will give negative IRQ numbers in return. It has been pointed out that returning 0 is NO_IRQ and that drivers should be amended to treat this as an error, but that is for the longer term: now let us repair the semantics.

2016-06-20can: at91_can: RX queue could get stuck at high bus loadWolfgang Grandegger
At high bus load it could happen that "at91_poll()" enters with all RX message boxes filled up. If then at the end the "quota" is exceeded as well, "rx_next" will not be reset to the first RX mailbox and hence the interrupts remain disabled.

2016-06-20can: c_can: Update D_CAN TX and RX functions to 32 bit - fix Altera Cyclone ↵Thor Thayer
access When testing CAN write floods on Altera's CycloneV, the first 2 bytes are sometimes 0x00, 0x00 or corrupted instead of the values sent. Also observed bytes 4 & 5 were corrupted in some cases. The D_CAN Data registers are 32 bits and changing from 16 bit writes to 32 bit writes fixes the problem. Testing performed on Altera CycloneV (D_CAN). Requesting tests on other C_CAN & D_CAN platforms.
