The patch titled Subject: drivers/firmware/broadcom/bcm47xx_nvram.c: fix incorrect __ioread32_copy has been removed from the -mm tree. Its filename was drivers-firmware-broadcom-bcm47xx_nvramc-fix-incorrect-__ioread32_copy.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Aaro Koskinen <aaro.koskinen@xxxxxx> Subject: drivers/firmware/broadcom/bcm47xx_nvram.c: fix incorrect __ioread32_copy Commit 1f330c327900 ("drivers/firmware/broadcom/bcm47xx_nvram.c: use __ioread32_copy() instead of open-coding") switched to use a generic copy function, but failed to notice that the header pointer is updated between the two copies, resulting in bogus data being copied in the latter one. Fix by keeping the old header pointer. The patch fixes totally broken networking on WRT54GL router (both LAN and WLAN interfaces fail to probe).
