| Subject: [PATCH] Fix Ultrastor asm snippet |
| |
| commit fad4dab5e44e10acf6b0235e469cb8e773b58e31 upstream. |
| |
| Commit 1292500b replaced |
| |
| "=m" (*field) : "1" (*field) |
| |
| with |
| |
| "=m" (*field) : |
| |
| with comment "The following patch fixes it by using the '+' operator on |
| the (*field) operand, marking it as read-write to gcc." |
| '+' was actually forgotten. This really puts it. |
