[PATCH v2] usb: pci-quirks: Reduce the length of a spinlock section in usb_amd_find_chipset_info()
From: Christophe JAILLET
Date: Thu Mar 23 2023 - 15:40:37 EST
'info' is local to the function. There is no need to zeroing it within
a spin_lock section. Moreover, there is no need to explicitly initialize
the .need_pll_quirk field.
Initialize the structure when defined and remove the now useless memset().
