Subject: [PATCH v6 04/10] powerpc: Reference parameter in MSR_TM_ACTIVE() macro
Date: Sat, 20 Feb 2021 19:23:55 -0600 [thread overview]
Message-ID: <20210221012401.22328-5-cmr@codefail.de> (raw)
In-Reply-To: <20210221012401.22328-1-cmr@codefail.de>
Unlike the other MSR_TM_* macros, MSR_TM_ACTIVE does not reference or
use its parameter unless CONFIG_PPC_TRANSACTIONAL_MEM is defined. This
causes an 'unused variable' compile warning unless the variable is also
guarded with CONFIG_PPC_TRANSACTIONAL_MEM.
Reference but do nothing with the argument in the macro to avoid a
potential compile warning.
