[PATCH 5.4 079/434] media: max2175: Fix build error without CONFIG_REGMAP_I2C

[Greg Kroah-Hartman]

From: YueHaibing <yuehaibing@xxxxxxxxxx>

[ Upstream commit 36756fbff1e4a31d71d262ae6a04a20b38efa874 ]

If CONFIG_REGMAP_I2C is not set, building fails:

drivers/media/i2c/max2175.o: In function `max2175_probe':
max2175.c:(.text+0x1404): undefined reference to `__devm_regmap_init_i2c'

Select REGMAP_I2C to fix this.
