| Subject: iio: health: max30100: fixed parenthesis around FIFO count check |
| |
| From: Matt Ranostay <matt@ranostay.consulting> |
| |
| commit 828f84ee8f84710ea1818b3565add268bcb824c8 upstream. |
| |
| FIFO was being read every sample after the "almost full" state was |
| reached. This was due to an incorrect placement of the parenthesis |
| in the while condition check. |
| |
| Note - the fixes tag is not actually correct, but the fix in this patch |
| would also be needed for it to function correctly so we'll go with that |
| one. Backports should pick up both. |
