If anyone has any objections, please let me know. ------------------ From: Abdun Nihaal [ Upstream commit 6132d70d0890c03546f6970893fd71938efb2a2f ] In ath11k_dp_srng_setup(), the memory allocated for ring->vaddr_unaligned is not freed in the error paths that follow. Fix that by calling ath11k_dp_srng_cleanup() in those error paths. Compile tested only. Issue found using a prototype static analysis tool built on the LLVM compiler infrastructure.
