Quentin Casasnovas 197b3975f4 regmap: fix kernel hang on regmap_bulk_write with zero val_count. ... Fixes commit 2f06fa04cf which was an incorrect backported version of commit d6b41cb060 upstream. If val_count is zero we return -EINVAL with map->lock_arg locked, which will deadlock the kernel next time we try to acquire this lock. This was introduced by f5942dd ("regmap: fix possible ZERO_SIZE_PTR pointer dereferencing error.") which improperly back-ported d6b41cb0. This issue was found during review of Ubuntu Trusty 3.13.0-40.68 kernel to prepare Ksplice rebootless updates. Fixes: f5942dd ("regmap: fix possible ZERO_SIZE_PTR pointer dereferencing error.")
