Subject: [PATCH] xhci: fix 'broken_suspend' placement in struct xchi_hcd
Date: Mon, 17 Dec 2018 14:37:40 +0100 [thread overview]
Message-ID: <20181217133740.5342-1-nsaenzjulienne@suse.de> (raw)
As commented in the struct's definition there shouldn't be anything
underneath it's 'priv[0]' member as it would break some macros.
The patch converts the broken_suspend into a bit-field and relocates it
next to to the rest of bit-fields.
Fixes: a7d57abcc8a5 ("xhci: workaround CSS timeout on AMD SNPS 3.0 xHC")
Reported-by: Oliver Neukum <oneukum@suse.com>
