Subject: soc/qbman: Fix implicit header dependency now causing build fails
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4512c7bccb7794fb6d6ff37ae449154413bd4963;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

soc/qbman: Fix implicit header dependency now causing build fails

In commit 461a6946b1f9 ("iommu: Remove pci.h include from
trace/events/iommu.h") that header shuffle uncovered an implicit
include in this driver, manifesting as:

    CC      drivers/soc/fsl/qbman/qman_portal.o
    drivers/soc/fsl/qbman/qman_portal.c: In function 'qman_portal_probe':
    drivers/soc/fsl/qbman/qman_portal.c:299:2: error: implicit declaration of function 'dma_set_mask'
    drivers/soc/fsl/qbman/qman_portal.c:299:2: error: implicit declaration of function 'DMA_BIT_MASK'
        if (dma_set_mask(dev, DMA_BIT_MASK(40))) {
        ^

on the corenet32_smp_defconfig (and 64 bit respectively.)  The above
commit was singled out via git bisect.

The header it was implictly relying on getting was dma-mapping.h - so
we explicitly add it here.
