During startup, CDRMAtomicImpl::reset() may emit a call to method commit of a CDRMAtomicRequest instance with member "conn" uninitialized, leading to a segfault. Validate the the pointer before dereference it as a workaround. Fixes: 55ac962 ("DRM: preliminary atomic support") Closes: hyprwm#107 Signed-off-by: Yao Zi <ziyao@disroot.org>
