Subject: [PATCH] soc: qcom: use assign_bit() where applicable
Date: Fri, 18 Sep 2026 22:18:32 +0800	[thread overview]
Message-ID: <20260918141833.3023124-1-peng.fan@oss.nxp.com> (raw)

From: Peng Fan <peng.fan@nxp.com>

Convert open-coded if/else with set_bit/clear_bit and their
non-atomic __set_bit/__clear_bit variants to the assign_bit/__assign_bit
API.

Done with Coccinelle semantic patch:
    // set_bit -> clear_bit => assign_bit

    @@
    expression cond, bit, addr;
    @@

    -if (cond)
    -        set_bit(bit, addr);
    -else
    -        clear_bit(bit, addr);
    +assign_bit(bit, addr, cond);

    // clear_bit -> set_bit => assign_bit

    @@
    expression cond, bit, addr;

    -        set_bit(bit, addr);
