From: Jarkko Nikula Date: Mon, 6 Jun 2016 11:26:21 +0000 (+0300) Subject: i2c: core: Cleanup I2C ACPI namespace X-Git-Tag: v4.14-rc1~2810^2~26 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a7003b65801e17a19617a509b2dbae3442ddd709;p=platform%2Fkernel%2Flinux-rpi.git i2c: core: Cleanup I2C ACPI namespace I2C ACPI enumeration was originally implemented in another module under drivers/acpi/ but was later moved into i2c-core with added support for I2C ACPI operation region. Rename these acpi_i2c_ prefixed functions, structures and defines in i2c-core to i2c_acpi_ in order to have more consistent name space.
