regulator: Fixes for 4.19
A collection of fairly minor bug fixes here, a couple of driver specific ones plus two core fixes. There's one fix for the new suspend state code which fixes some confusion with constant values that are supposed to indicate noop operation and another fixing a race condition with the creation of sysfs files on new regulators. -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAluuL04THGJyb29uaWVA a2VybmVsLm9yZwAKCRAk1otyXVSH0GdVB/9AWbmIA8iNJDo/CETEZ9UiOvEFXSO8 vRk+WcU4vtPo4qp27ylYRh9dKjWczEq8dKpe4YmaLjv4HX5MggLiwO1cLl44+q6y AKZYK1FvGR1yExP3adE4XEC03jD21909mkLCNRawCVh+Iorp4r5CA6ahNfzT0flI Eo5nKi4zN/0WSjxcoDdqUQ7oIivlmxiC8HYZyluS7f6UV0rcQXeqdXKqs6utPUxD w4MLQriPqG7R0g75XqoRB7hVcZBO4m/NRi6SMGQtF1WG1unpl+iCnxRa0WXHi1th nMg900nucgIe6gWBxMocWbyXsFj3+CrWlCB4BxVW8+pe8VyLFtYnPUA5 =yAAv -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAluuMasTHGJyb29uaWVA a2VybmVsLm9yZwAKCRAk1otyXVSH0NPZB/0X1e0JWK819dT5HWgNa6E2391fn1Qj eY89u0cJj+3gom3QyOKCupcjEIumPHVYjiCsIEVipH+vefcuzgyUkRHhBZsSFgyp 90sVHKywg5pcxi6em/wuStzkXA84HjCVPJ4nDd6fnE6Ew7NDpP0/FPkpt7PwqlFy b56pg/iK6YFhgXLlJMi6k7TGb/NG9M0qZzrb5UvTIbqVw9IRsqQrLN6YSaqhUFwe hwonne4bMPl4DroVBGDz15djFv0Re7DxJuhAErJ/Fafzq5SX1zAPzkJ6peJnSdyF 2fUv6596nhNKVqAvMF5514kBq+JeFB13YS4S2Xm2Dm/rQ1P9G8XSfzQG =YPYr -----END PGP SIGNATURE----- Merge tag 'regulator-v4.19-rc5' into regulator-bd718xx regulator: Fixes for 4.19 A collection of fairly minor bug fixes here, a couple of driver specific ones plus two core fixes.
