Subject: [PATCH] pflash_cfi01: Fix warning caused by unreachable code
|
|
|
5544c1 |
|
|
|
5544c1 |
Report from smatch:
|
|
|
5544c1 |
hw/pflash_cfi01.c:431 pflash_write(180) info: ignoring unreachable code.
|
|
|
5544c1 |
|
|
|
5544c1 |
Instead of removing the return statement after the switch statement,
|
|
|
5544c1 |
the patch replaces the return statements in the switch statement by
|
|
|
5544c1 |
break statements. Other switch statements in the same code do it also
|
|
|
5544c1 |
like that.
