clkdev DEV ID information is limited to an array of 20 bytes (MAX_DEV_ID). It is possible that the ID could be longer than that. If so, the lookup will fail because the "real ID" will not match the copied value. For instance, generating a device name for the I2C Designware module using the PCI ID can result in a name of: i2c_designware.39424 clkdev_create() will store: i2c_designware.3942 The stored name is one off and will not match correctly during probe. Increase the size of the ID to allow for a longer name. Reviewed-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: Michael J.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
