X-Git-Tag: v5.10.7~1740^2~6 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=41dd70b368278f3ac789bed25bc810f764e14bbf;p=platform%2Fkernel%2Flinux-rpi.git USB: PHY: JZ4770: Fix static checker warning. The commit 2a6c0b82e651 ("USB: PHY: JZ4770: Add support for new Ingenic SoCs.") introduced the initialization function for different chips, but left the relevant code involved in the resetting process in the original function, resulting in uninitialized variable calls. Fixes: 2a6c0b82e651 ("USB: PHY: JZ4770: Add support for new Ingenic SoCs.").
