This is a note to let you know that I've just added the patch titled irqdomain: Change the type of 'size' in __irq_domain_add() to be consistent to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: irqdomain-change-the-type-of-size-in-__irq_domain_ad.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit bfa01f225d22fffdf704f267bcb38e4f9735562b Author: Bixuan Cui <cuibixuan@xxxxxxxxxx> Date: Thu Sep 16 10:52:03 2021 +0800 irqdomain: Change the type of 'size' in __irq_domain_add() to be consistent [ Upstream commit 20c36ce2164f1774b487d443ece99b754bc6ad43 ] The 'size' is used in struct_size(domain, revmap, size) and its input parameter type is 'size_t'(unsigned int). Changing the size to 'unsigned int' to make the type consistent.
