Merge tag 'hwlock-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux
Pull hwspinlock updates from Bjorn Andersson:
"This updates sprd and srm32 drivers to use struct_size() instead of
their open-coded equivalents. It also cleans up the omap dt-bindings
example"
* tag 'hwlock-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux:
hwspinlock: sprd: Use struct_size() helper in devm_kzalloc()
hwspinlock: stm32: Use struct_size() helper in devm_kzalloc()
dt-bindings: hwlock: omap: Remove redundant binding example
