Subject: [PATCH]     Fix implicit cast warning in test_klp_state.c
Date: Sat, 17 Feb 2024 04:21:26 +0530
Message-ID: <20240216225126.454999-1-shresthprasad7@gmail.com>
Precedence: bulk

    The function `klp_get_state` returns an `int` value, but the variable
    `loglevel_state` is of type `struct klp_state *` and thus does an
    implicit cast. Explicitly casting these values fixes:

            - warning: assignment to ‘struct klp_state *’ from ‘int’
	    makes pointer from integer without a cast [-Wint-conversion]

    on lines 38, 55, 68 and 80 of test_klp_state.c
