| Subject: [PATCH] i2c: pca-platform: Use platform_irq_get_optional |
| |
| commit 14c1fe699cad9cb0acda4559c584f136d18fea50 upstream. |
| |
| The interrupt is not required so use platform_irq_get_optional() to |
| avoid error messages like |
| |
| i2c-pca-platform 22080000.i2c: IRQ index 0 not found |
