Subject: [PATCH v2 4/7] remoteproc: Use kstrdup_const() rather than kstrup()
Date: Wed, 15 Apr 2020 14:48:55 -0600 [thread overview]
Message-ID: <20200415204858.2448-5-mathieu.poirier@linaro.org> (raw)
Message-ID: <20200415204855.9kzLHlUWPKn-m8OYweflGMBpL4adEx_DsGDLBmncAuI@z> (raw)
In-Reply-To: <20200415204858.2448-1-mathieu.poirier@linaro.org>
For cases where @firmware is declared "const char *", use function
kstrdup_const() to avoid needlessly creating another copy on the
heap.
Suggested-by: Bjorn Andersson <bjorn.andersson@linaro.org>
