      pinctrl: core: make sure strcmp() doesn't get a null parameter · 54a58185
      Yanjiang Jin authored
      Some drivers, for example, QCOM's qdf2xxx, set groups[gpio].name only
      when gpio is valid, and leave invalid gpio names as null.
      If we want to access the sys node "pinconf-groups",
      pinctrl_get_group_selector() -> get_group_name() may return a null
      pointer if group_selector is invalid, then the below Kernel panic
      would happen since strcmp() uses this null pointer to do comparison.

      This is the 4.19-rc6 release
      
      I needed to merge this in because of extensive conflicts in
      the MSM and Intel pin control drivers. I know how to resolve
      them, so let's do it like this.

         A set of fixes that should go into this release. This pull request

           previous fix from this series wasn't complete, hence reverted, and
           this one should hopefully be it. (Boris Ostrovsky)
      
         - Fix for an elevator drain warning with SMR devices, which is
           triggered when you switch schedulers (Damien)
      
         - bcache deadlock fix (Guoju Fang)
      
         - Fix for the block unplug tracepoint, which has had the
           timer/explicit flag reverted since 4.11 (Ilya)
      
         - Fix a regression in this series where the blk-mq timeout hook is
           invoked with the RCU read lock held, hence preventing it from
           blocking (Keith)
      
         - NVMe pull from Christoph, with a single multipath fix (Susobhan Dey)"

      cpufreq: qcom-kryo: Fix section annotations · d51aea13
      Nathan Chancellor authored
      There is currently a warning when building the Kryo cpufreq driver into
      the kernel image:
      
      WARNING: vmlinux.o(.text+0x8aa424): Section mismatch in reference from
      the function qcom_cpufreq_kryo_probe() to the function
      .init.text:qcom_cpufreq_kryo_get_msm_id()
      The function qcom_cpufreq_kryo_probe() references
      the function __init qcom_cpufreq_kryo_get_msm_id().
      This is often because qcom_cpufreq_kryo_probe lacks a __init
      annotation or the annotation of qcom_cpufreq_kryo_get_msm_id is wrong.
      
      Remove the '__init' annotation from qcom_cpufreq_kryo_get_msm_id
      so that there is no more mismatch warning.
      
      Additionally, Nick noticed that the remove function was marked as
      '__init' when it should really be marked as '__exit'.
      
      Fixes: 46e2856b (cpufreq: Add Kryo CPU scaling driver)
      Fixes: 5ad7346b (cpufreq: kryo: Add module remove and exit)
