Merge tag 'hwlock-v6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux
Pull hwspinlock updates from Bjorn Andersson: "Convert u8500 and omap drivers to void-returning remove. Complete the support for representing the Qualcomm TCSR mutex as a mmio device, and check the return value of devm_regmap_field_alloc() in the same" * tag 'hwlock-v6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: hwspinlock: qcom: add missing regmap config for SFPB MMIO implementation hwspinlock: u8500: Convert to platform remove callback returning void hwspinlock: omap: Convert to platform remove callback returning void hwspinlock: omap: Emit only one error message for errors in .remove() hwspinlock: add a check of devm_regmap_field_alloc in qcom_hwspinlock_probe
