Merge tag 'samsung-fixes-6.16' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into arm/fixes
Samsung SoC fixes for v6.16 1. Correct CONFIG option in arm64 defconfig enabling the Qualcomm SoC SNPS EUSB2 phy driver, because Kconfig entry was renamed when changing the driver to a common one, shared with Samsung SoC, thus defconfig lost that driver effectively. 2. Exynos ACPM: Fix timeouts happening with multiple requests. * tag 'samsung-fixes-6.16' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: firmware: exynos-acpm: fix timeouts on xfers handling arm64: defconfig: update renamed PHY_SNPS_EUSB2
