staging: erofs: add requirements field in superblock

2019-06-17T20:58:58Z

There are some backward incompatible features pending for months, mainly due to on-disk format expensions. However, we should ensure that it cannot be mounted with old kernels. Otherwise, it will causes unexpected behaviors.

staging: iio: adt7316: Fix build errors when GPIOLIB is not set

2019-06-08T11:54:47Z

On x86_64 when GPIOLIB is not set the following build errors are seen: drivers/staging/iio/addac/adt7316.c:947:3: error: implicit declaration of function 'gpiod_set_value' [-Werror=implicit-function-declaration] drivers/staging/iio/addac/adt7316.c:1805:2: error: implicit declaration of function 'irqd_get_trigger_type' [-Werror=implicit-function-declaration] These functions are provided by the and headers, so include them to fix these build errors. While at it, remove as this driver is a GPIO consumer and not a GPIO driver.

staging:iio:ad7150: fix threshold mode config bit

2019-05-27T09:52:30Z

According to the AD7150 configuration register description, bit 7 assumes value 1 when the threshold mode is fixed and 0 when it is adaptive, however, the operation that identifies this mode was considering the opposite values. This patch renames the boolean variable to describe it correctly and properly replaces it in the places where it is used.

staging: kpc2000: Add dependency on MFD_CORE to kconfig symbol 'KPC2000'

2019-05-24T07:41:09Z

The kpc2000 core makes calls against functions conditionally exported upon selection of the kconfig symbol MFD_CORE. Therefore, the kpc2000 core depends upon the mfd_core, and that dependency must be tracked in Kconfig to avoid potential build issues. Signed-off-by: Geordan Neukum Signed-off-by: Greg Kroah-Hartman

staging: vc04_services: prevent integer overflow in create_pagelist()

2019-05-20T07:26:04Z

The create_pagelist() "count" parameter comes from the user in vchiq_ioctl() and it could overflow. If you look at how create_page() is called in vchiq_prepare_bulk_data(), then the "size" variable is an int so it doesn't make sense to allow negatives or larger than INT_MAX. I don't know this code terribly well, but I believe that typical values of "count" are typically quite low and I don't think this check will affect normal valid uses at all. The "pagelist_size" calculation can also overflow on 32 bit systems, but not on 64 bit systems. I have added an integer overflow check for that as well. The Raspberry PI doesn't offer the same level of memory protection that x86 does so these sorts of bugs are probably not super critical to fix.
