Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
![]() Christian and Kees both pointed out that this is a bit sloppy to open-code both places, and Christian points out that we leave a dangling pointer to ->notif if file allocation fails. Since we check ->notif for null in order to determine if it's ok to install a filter, this means people won't be able to install a filter if the file allocation fails for some reason, even if they subsequently should be able to. To fix this, let's hoist this free+null into its own little helper and use it.

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.
