[PATCH v1] soc: samsung: usi: prevent wrong bits inversion during unconfiguring
From: Ivaylo Ivanov
Date: Sun Apr 13 2025 - 12:38:10 EST
Instead of setting bit 1 (USI_OPTION_CLKSTOP_ON) during USI unconfiguring,
all the other bits in the USI_OPTION register get inverted, which
should not happen as that means the clock will keep getting provided
to the USI IP. Remove the unnecessary tilde.
Fixes: 11e77776b58a ("soc: samsung: usi: add a routine for unconfiguring the ip")
