Subject: [PATCH 7/8] parisc: add missing export of __cmpxchg_u8()
Date: Tue,  2 Apr 2024 00:28:34 -0400	[thread overview]
Message-ID: <20240402042835.11815-7-viro@zeniv.linux.org.uk> (raw)
In-Reply-To: <20240402042835.11815-1-viro@zeniv.linux.org.uk>

__cmpxchg_u8() had been added (initially) for the sake of
drivers/phy/ti/phy-tusb1210.c; the thing is, that drivers is
modular, so we need an export

Fixes: b344d6a83d01 "parisc: add support for cmpxchg on u8 pointers"
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
