Subject: [PATCH] soc: qcom: pdr: Remove impossible error condition
Date: Wed, 15 Apr 2020 11:59:55 +0530 [thread overview]
Message-ID: <20200415062955.21439-1-sibis@codeaurora.org> (raw)
The patch fbe639b44a82: "soc: qcom: Introduce Protection Domain
Restart helpers" leads to the following static checker warning:
drivers/soc/qcom/pdr_interface.c:158 pdr_register_listener()
'(resp.curr_state < (-((~0 >> 1)) - 1)) => (s32min-s32max < s32min)'
These are casted to int so they can't be outside of int range.
Fixes: fbe639b44a82 ("soc: qcom: Introduce Protection Domain Restart helpers")
