| Subject: serial: sprd: adjust TIMEOUT to a big value |
| |
| From: Wei Qiao <wei.qiao@spreadtrum.com> |
| |
| commit e1dc9b08051a2c2e694edf48d1e704f07c7c143c upstream. |
| |
| SPRD_TIMEOUT was 256, which is too small to wait until the status |
| switched to workable in a while loop, so that the earlycon could |
| not work correctly. |
