| Subject: [PATCH 0831/1795] mmc: tmio: remove useless TMIO_MASK_CMD handling in |
| tmio_mmc_host_probe() |
| |
| TMIO_MASK_CMD is properly enabled in tmio_mmc_start_command(). |
| |
| We have no reason to set it up in tmio_mmc_host_probe(). (If we |
| really wanted to set it in the probe, we would have to do likewise |
| when resuming.) |
| |
| Even worse, the following code is extremely confusing: |
| |
| _host->sdcard_irq_mask &= ~irq_mask; |
| |
| The logic is opposite between "->sdcard_irq_mask" and "irq_mask". |
| The intention is not clear at a glance. |
