[PATCH -next] PCI: brcmstb: Fix missing mutex_init()
From: Wei Yongjun <hidden>
Date: 2020-01-19 02:36:15
Also in:
kernel-janitors, linux-pci
Subsystem:
broadcom bcm2711/bcm2835 arm architecture, broadcom bcm7xxx arm architecture, broadcom stb pcie driver, pci native host bridge and endpoint drivers, pci subsystem, the rest · Maintainers:
Florian Fainelli, Jim Quinlan, Lorenzo Pieralisi, Krzysztof Wilczyński, Manivannan Sadhasivam, Bjorn Helgaas, Linus Torvalds
The driver allocates the mutex but not initialize it.
Use mutex_init() on it to initialize it correctly.
This is detected by Coccinelle semantic patch.
Fixes: 72af6f6f0d13 ("PCI: brcmstb: Add MSI support")
