Clément Le Goffic a6e099cda2 dmaengine: stm32-mdma: initialize m2m_hw_period and ccr to fix warnings ... [ Upstream commit aaf3bc0265744adbc2d364964ef409cf118d193d ] m2m_hw_period is initialized only when chan_config->m2m_hw is true. This triggers a warning: ‘m2m_hw_period’ may be used uninitialized [-Wmaybe-uninitialized] Although m2m_hw_period is only used when chan_config->m2m_hw is true and ignored otherwise, initialize it unconditionally to 0. ccr is initialized by stm32_mdma_set_xfer_param() when the sg list is not empty. This triggers a warning: ‘ccr’ may be used uninitialized [-Wmaybe-uninitialized] Indeed, it could be used uninitialized if the sg list is empty. Initialize it to 0.
