[ Upstream commitc871c199ac] When __regmap_init() is called from __regmap_init_i2c() and __regmap_init_spi() (and their devm versions), the bus argument obtained from regmap_get_i2c_bus() and regmap_get_spi_bus(), may be allocated using kmemdup() to support quirks. In those cases, the bus->free_on_exit field is set to true. However, inside __regmap_init(), buf is not freed on any error path. This could lead to a memory leak of regmap_bus when __regmap_init() fails. Fix that by freeing bus on error path when free_on_exit is set.

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 reStructuredText 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.
