X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e4592fdd070ca77c74491ee6b61e31ac427ebf8c;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

staging,spear_adc: Add dependency on HAS_IOMEM

On archs like S390 or um this driver cannot build nor work.
Make it depend on HAS_IOMEM to bypass build failures.

drivers/staging/iio/adc/spear_adc.c: In function ‘spear_adc_probe’:
drivers/staging/iio/adc/spear_adc.c:393:2: error: implicit declaration of function ‘iounmap’ [-Werror=implicit-function-declaration
