linux-next: build failure after merge of the pm tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

After merging the pm tree, today's linux-next build (x86_84 allmodconfig)
failed like this:

sound/soc/sh/rz-ssi.c: In function 'rz_ssi_probe':
sound/soc/sh/rz-ssi.c:1023:2: error: ignoring return value of 'pm_runtime_resume_and_get' declared with attribute 'warn_unused_result' [-Werror=unused-result]
 1023 |  pm_runtime_resume_and_get(&pdev->dev);
      |  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

Caused by commit

  877d952c261e ("PM: runtime: Annotate pm_runtime_resume_and_get() as __must_check")

This also produced the following warnings in my arm multi_v7_defconfig
build:

drivers/crypto/stm32/stm32-hash.c: In function 'stm32_hash_hw_init':
drivers/crypto/stm32/stm32-hash.c:816:2: warning: ignoring return value of 'pm_runtime_resume_and_get' declared with attribute 'warn_unused_result' [-Wunused-result]

  545 |  pm_runtime_resume_and_get(cryp->dev);
      |  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I have used the pm tree from next-20211224 for today.
