Subject: [PATCH] adc: stm32: Fix warnings when compiling with W=1
This patch solves the following warnings:
drivers/adc/stm32-adc-core.c: In function 'stm32h7_adc_clk_sel':
warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
for (i = 0; i < ARRAY_SIZE(stm32h7_adc_ckmodes_spec); i++) {
