  • c5857e3f9   pwm: brcmstb: Fix check of devm_ioremap_resource() return code ... Browse Code »

    The change fixes potential oops while accessing iomem on invalid address
    if devm_ioremap_resource() fails due to some reason.

    The devm_ioremap_resource() function returns ERR_PTR() and never returns
    NULL, which makes useless a following check for NULL.

    Add support for the BCM7038-style PWM controller found in all BCM7xxx STB SoCs.
    This controller has a hardcoded 2 channels per controller, and cascades a
    variable frequency generator on top of a fixed frequency generator which offers
    a range of a 148ns period all the way to ~622ms periods.
