From: Jorge Ramirez-Ortiz Date: Mon, 22 Apr 2019 17:28:24 +0000 (+0200) Subject: regulator: core: simplify return value on suported_voltage X-Git-Tag: v5.2-rc5~28^2~1 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=498209445124;p=users%2Fhch%2Fdma-mapping.git regulator: core: simplify return value on suported_voltage All the current clients of this API assume that 0 corresponds to a failure and non-zero to a pass therefore ignoring the need to handle a negative error code. This commit modifies the API to follow that standard since returning a negative (EINVAL) doesn't seem to provide enough value to justify the need to handle it.
