>Subject: [PATCH] qla2xxx: Wait for FLASH write-protection to complete after a write.
>
>Some flash parts have a slow enable write-protection (WP)
>operation whereby subsequent FLASH accesses would fail if the WP
>operation had not completed.  Software now polls the SPI's
>status-register for WP completion.
