With such name, the directory creation (silently) fails and the debugfs entry ends up being created at the debugfs root. With this change, the new clock names are: - c1108680.adc#adc_div - c1108680.adc#adc_en This matches the clock naming scheme used in the PWM, Ethernet and MMC drivers. It also fixes the problem with debugfs. The idea is shamelessly taken from commit b96e9eb62841c5 ("pwm: meson: Fix mux clock names").
