| Subject | [PATCH 3/3] coresight: tmc: Remove duplicate memset |
| Message-ID | <sm0VH-1H1-7@gated-at.bofh.it> |
The tmc_etr_enable_hw() fills the buffer with 0's before enabling the hardware. So, we don't need an explicit memset() in tmc_enable_etr_sink_sysfs() before calling the tmc_etr_enable_hw(). This patch removes the explicit memset from tmc_enable_etr_sink_sysfs.
