Subject: [PATCH v1 1/1] serial: 8250_ce4100: Fix CONFIG_SERIAL_8250=n build
Date: Wed, 16 Jul 2025 12:44:33 +0300 [thread overview]
Message-ID: <20250716094433.1611477-1-andriy.shevchenko@linux.intel.com> (raw)
On i386, when
CONFIG_X86_INTEL_CE=y
# CONFIG_SERIAL_8250 is not set
will try to compile the driver and use the stub simultaneously.
This breaks the build. Fix it by making sure that the driver
compiles only when CONFIG_SERIAL_8250 is also enabled.
Fixes: acc902de05b2 ("serial: 8250: Move CE4100 quirks to a module under 8250 driver")
Reported-by: Randy Dunlap <rdunlap@infradead.org>
Closes: https://lore.kernel.org/r/cdf4ee46-7bf8-4379-9245-fed9db72e7e8@infradead.org
