Subject: [PATCH v4 28/41] rtc: add HAS_IOPORT dependencies
Date:   Tue, 16 May 2023 13:00:24 +0200
Message-Id: <20230516110038.2413224-29-schnelle@linux.ibm.com>
In-Reply-To: <20230516110038.2413224-1-schnelle@linux.ibm.com>

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. We thus need to add HAS_IOPORT as dependency for
those drivers using them.

Note: The HAS_IOPORT Kconfig option was added in v6.4-rc1 so
      per-subsystem patches may be applied independently
