fjes: Add missing iounmap in fjes_hw_init()

2026-01-19T12:11:59+00:00

commit 15ef641a0c6728d25a400df73922e80ab2cf029c upstream. In error paths, add fjes_hw_iounmap() to release the resource acquired by fjes_hw_iomap(). Add a goto label to do so.

minmax: make generic MIN() and MAX() macros available everywhere

2025-10-29T13:01:16+00:00

[ Upstream commit 1a251f52cfdc417c84411a056bc142cbd77baef4 ] This just standardizes the use of MIN() and MAX() macros, with the very traditional semantics. The goal is to use these for C constant expressions and for top-level / static initializers, and so be able to simplify the min()/max() macros. These macro names were used by various kernel code - they are very traditional, after all - and all such users have been fixed up, with a few different approaches: - trivial duplicated macro definitions have been removed Note that 'trivial' here means that it's obviously kernel code that already included all the major kernel headers, and thus gets the new generic MIN/MAX macros automatically. - non-trivial duplicated macro definitions are guarded with #ifndef This is the "yes, they define their own versions, but no, the include situation is not entirely obvious, and maybe they don't get the generic version automatically" case. - strange use case #1 A couple of drivers decided that the way they want to describe their versioning is with #define MAJ 1 #define MIN 2 #define DRV_VERSION __stringify(MAJ) "." __stringify(MIN) which adds zero value and I just did my Alexander the Great impersonation, and rewrote that pointless Gordian knot as #define DRV_VERSION "1.2" instead. - strange use case #2 A couple of drivers thought that it's a good idea to have a random 'MIN' or 'MAX' define for a value or index into a table, rather than the traditional macro that takes arguments. These values were re-written as C enum's instead. The new function-line macros only expand when followed by an open parenthesis, and thus don't clash with enum use. Happily, there weren't really all that many of these cases, and a lot of users already had the pattern of using '#ifndef' guarding (or in one case just using '#undef MIN') before defining their own private version that does the same thing. I left such cases alone. Cc: David Laight Cc: Lorenzo Stoakes Signed-off-by: Linus Torvalds Signed-off-by: Eliav Farber Signed-off-by: Greg Kroah-Hartman

fjes: fix memleaks in fjes_hw_setup

2024-02-23T07:41:57+00:00

[ Upstream commit f6cc4b6a3ae53df425771000e9c9540cce9b7bb1 ] In fjes_hw_setup, it allocates several memory and delay the deallocation to the fjes_hw_exit in fjes_probe through the following call chain: fjes_probe |-> fjes_hw_init |-> fjes_hw_setup |-> fjes_hw_exit However, when fjes_hw_setup fails, fjes_hw_exit won't be called and thus all the resources allocated in fjes_hw_setup will be leaked. In this patch, we free those resources in fjes_hw_setup and prevents such leaks.

fjes: Check for error irq

2021-12-29T11:25:57+00:00

[ Upstream commit db6d6afe382de5a65d6ccf51253ab48b8e8336c3 ] I find that platform_get_irq() will not always succeed. It will return error irq in case of the failure. Therefore, it might be better to check it if order to avoid the use of error irq.
