Subject: [PATCH] mmc: sdhci-of-arasan: Add missed checks for devm_clk_register()
Date: Tue, 9 Jun 2020 00:22:26 +0800 [thread overview]
Message-ID: <20200608162226.3259186-1-hslester96@gmail.com> (raw)
These functions do not check the return value of devm_clk_register():
- sdhci_arasan_register_sdcardclk()
- sdhci_arasan_register_sampleclk()
Therefore, add the missed checks to fix them.
Fixes: c390f2110adf1 ("mmc: sdhci-of-arasan: Add ability to export card clock")
