Subject: [PATCH] soc: aspeed: Fix snoop_file_poll()'s return type
Date: Thu, 21 Nov 2019 15:48:51 +1030 [thread overview]
Message-ID: <20191121051851.268726-1-joel@jms.id.au> (raw)
From: Luc Van Oostenryck <luc.vanoostenryck@gmail.com>
snoop_file_poll() is defined as returning 'unsigned int' but the
.poll method is declared as returning '__poll_t', a bitwise type.
Fix this by using the proper return type and using the EPOLL
constants instead of the POLL ones, as required for __poll_t.
Fixes: 3772e5da4454 ("drivers/misc: Aspeed LPC snoop output using misc chardev")
