This is a note to let you know that I've just added the patch titled staging: greybus: power_supply: fix prop-descriptor request size to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-testing branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the staging-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From 47830c1127ef166af787caf2f871f23089610a7f Mon Sep 17 00:00:00 2001 From: Johan Hovold <johan@xxxxxxxxxx> Date: Thu, 4 Apr 2019 08:53:30 +0200 Subject: staging: greybus: power_supply: fix prop-descriptor request size Since moving the message buffers off the stack, the dynamically allocated get-prop-descriptor request buffer is incorrectly sized due to using the pointer rather than request-struct size when creating the operation. Fortunately, the pointer size is always larger than this one-byte request, but this could still cause trouble on the remote end due to the unexpected message size.
