Subject: [PATCH] rtc: i2c/spi: Avoid inclusion of REGMAP support when not needed
Date: Sun, 12 Jan 2020 18:13:49 +0100 [thread overview]
Message-ID: <20200112171349.22268-1-geert@linux-m68k.org> (raw)
Merely enabling I2C and RTC selects REGMAP_I2C and REGMAP_SPI, even when
no driver needs it. While the former can be moduler, the latter cannot,
and thus becomes built-in.
Fix this by moving the select statements for REGMAP_I2C and REGMAP_SPI
from the RTC_I2C_AND_SPI helper to the individual drivers that depend on
it.
Note that the comment for RTC_I2C_AND_SPI refers to SND_SOC_I2C_AND_SPI
for more information, but the latter does not select REGMAP_{I2C,SPI}
itself, and defers that to the individual drivers, too.
Fixes: 080481f54ef62121 ("rtc: merge ds3232 and ds3234")
