2018-03-15misc: mic: Release reference count and memory for VOP deviceArvind Yadav1-2/+4
Never directly free @dev after calling device_register(), even if it returned an error! Always use put_device() to give up the reference initialized. Release allocated memory for vop device in vop_release_dev(). Signed-off-by: Arvind Yadav <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2018-03-15devres: combine function devm_ioremap*Yisheng Xie1-40/+38
When I tried to use devm_ioremap function and review related code, I found devm_ioremap_* almost have the similar realize with each other, which can be combined. In the former version, I have tried to kill ioremap_cache to reduce the size of devres, which can not work for ioremap is not the same as ioremap_nocache in some ARCHs likes ia64. Therefore, as the suggestion of Christophe, I introduce a help function __devm_ioremap, let devm_ioremap* inline and call __devm_ioremap with different devm_ioremap_type. After apply the patch, the size of devres.o can be reduce from 8216 Bytes to 8052 Bytes in my compile environment.

2018-03-15block, char_dev: Use correct format specifier for unsigned intsSrivatsa S. Bhat2-10/+13
register_blkdev() and __register_chrdev_region() treat the major number as an unsigned int. So print it the same way to avoid absurd error statements such as: "... major requested (-1) is greater than the maximum (511) ..." (and also fix off-by-one bugs in the error prints).

2018-03-14fsi: master: Clarify master lifetimes & fix use-after-free in hub masterJeremy Kerr2-3/+33
Once we call fsi_master_unregister, the core will put_device, potentially freeing the hub master. This change adds a comment explaining the lifetime of an allocated fsi_master. We then add a reference from the driver to the hub master, so it stays around until we've finished ->remove().

2018-03-14fsi: Match fsi slaves and engines to available dt nodesJeremy Kerr4-0/+108
This change populates device tree nodes for scanned FSI slaves and engines. If the master populates ->of_node of the FSI master device, we'll look for matching slaves, and under those slaves we'll look for matching engines. This means that FSI drivers will have their ->of_node pointer populated if there's a corresponding DT node, which they can use for further device discover. Presence of device tree nodes is optional, and only required for fsi device drivers that need extra properties, or subordinate devices, to be enumerated.

2018-03-14dt-bindings: fsi: Add specification for FSI bussesJeremy Kerr1-0/+144
This change introduces a proposed layout for describing FSI busses in the device tree. While the bus is probe-able, we'd still like a method of describing subordinate (eg i2c) busses that are behind FSI devices. The FSI core will be responsible for matching probed slaves & engines to their device tree nodes, so the FSI device drivers' probe() functions will be passed a struct device with the appropriate of_node populated where a matching DT node is found.

2018-03-14fsi: master-gpio: Add external modeJeremy Kerr2-2/+86
This change introduces an 'external mode' for GPIO-based FSI masters, allowing the clock and data lines to be driven by an external source. For example, external mode is selected by a user when an external debug device is attached to the FSI pins. To do this, we need to set specific states for the trans, mux and enable GPIOs, and prevent access to clk & data from the FSI core code (by returning EBUSY). External mode is controlled by a sysfs attribute, so add the relevant information to Documentation/ABI/ Signed-off-by: Jeremy Kerr <[email protected]> Reviewed-by: Joel Stanley <[email protected]> Signed-off-by: Joel Stanley <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
