[PULL 11/17] linux-user: Add support for TYPE_LONG and TYPE_ULONG in do_

From: Laurent Vivier
Subject: [PULL 11/17] linux-user: Add support for TYPE_LONG and TYPE_ULONG in do_ioctl()
Date: Thu, 23 Jan 2020 09:22:21 +0100

From: Filip Bozuta <address@hidden>

Function "do_ioctl()" located in file "syscall.c" was missing
an option for TYPE_LONG and TYPE_ULONG. This caused some ioctls
to not be recognised because they had the third argument that was
of type 'long' or 'unsigned long'.

For example:

Since implemented ioctls RTC_IRQP_SET and RTC_EPOCH_SET
are of type IOW(writing type) that have unsigned long as
their third argument, they were not recognised in QEMU
before the changes of this patch.
