This has the same error-handling problem as patch 1/3. I have fixed
this up in the same manner while merging this, resulting in:

        if (has_cap(ACER_CAP_PLATFORM_PROFILE)) {
                err = acer_platform_profile_setup();
                if (err)
                        goto error_platform_profile;
        }

        if (has_cap(ACER_CAP_FAN_SPEED_READ)) {
                err = acer_wmi_hwmon_init();
                if (err)
                        goto error_hwmon;
        }

        return 0;

error_hwmon:
        if (platform_profile_support)
                platform_profile_remove();
error_platform_profile:
        acer_rfkill_exit();
error_rfkill:
        if (has_cap(ACER_CAP_BRIGHTNESS))
                acer_backlight_exit();

Thank you for your patch, I've applied this patch to my review-hans 
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans
