Subject: [PATCH v4 02/41] ata: add HAS_IOPORT dependencies
Date: Tue, 16 May 2023 12:59:58 +0200	[thread overview]
Message-ID: <20230516110038.2413224-3-schnelle@linux.ibm.com> (raw)
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.

Co-developed-by: Arnd Bergmann <arnd@kernel.org>

Acked-by: Damien Le Moal <damien.lemoal@opensource.wdc.com>

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