coproc entry is initialized during NX probe on power9, but not on P8. nx842_delete_coprocs() is used for both and frees receive window if it is allocated. Getting crash for rmmod on P8 since coproc->vas.rxwin is not initialized. This patch replaces kmalloc with kzalloc in nx842_powernv_probe() Signed-off-by: Haren Myneni <haren@linux.ibm.com> Acked-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/1587114163.2275.1110.camel@hbabu-laptop
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.
