[PATCH 6.1 059/141] usb: pci-quirks: Reduce the length of a spinlock section in usb_amd_find_chipset_info()

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

 



6.1-stable review patch.  If anyone has any objections, please let me know.

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit c03ff66dc0e0cbad9ed0c29500843e1da8533118 ]

'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().
