Subject: [PATCH 4.4 07/31] i2c: mux: fix up dependencies
Date: Thu, 24 Nov 2016 15:55:28 +0100 [thread overview]
Message-ID: <20161124145447.353739897@linuxfoundation.org> (raw)
In-Reply-To: <20161124145446.993225208@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Walleij <linus.walleij@linaro.org>
commit 93d710a65ef02fb7fd48ae207e78f460bd7a6089 upstream.
We get the following build error from UM Linux after adding
an entry to drivers/iio/gyro/Kconfig that issues "select I2C_MUX":
ERROR: "devm_ioremap_resource"
[drivers/i2c/muxes/i2c-mux-reg.ko] undefined!
ERROR: "of_address_to_resource"
[drivers/i2c/muxes/i2c-mux-reg.ko] undefined!
It appears that the I2C mux core code depends on HAS_IOMEM
for historical reasons, while CONFIG_I2C_MUX_REG does *not*
have a direct dependency on HAS_IOMEM.
This creates a situation where a allyesconfig or allmodconfig
for UM Linux will select I2C_MUX, and will implicitly enable
I2C_MUX_REG as well, and the compilation will fail for the
register driver.
Fix this up by making I2C_MUX_REG depend on HAS_IOMEM and
removing the dependency from I2C_MUX.
