| Subject: [PATCH] dmaengine: ipu: Make sure the interrupt routine checks all |
| interrupts. |
| |
| commit adee40b265d7568296e218f079f478197ffa15bf upstream. |
| |
| Commit 3d8cc00073d6 ("dmaengine: ipu: Consolidate duplicated irq handlers") |
| consolidated the two interrupts routines into one, but the remaining |
| interrupt routine only checks the status of the error interrupts, not the |
| normal interrupts. |
| |
| This patch fixes that problem (tested on i.MX31 PDK board). |
