Subject: greybus: raw: Print expected/actual payload size on mismatch
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7fea641c94d645bf30712cb6e6c498597c7e5634;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

greybus: raw: Print expected/actual payload size on mismatch

Print (expected-payload-size actual-payload-size), when the size doesn't
match for requests received by the module. This gives more details
required for debugging the issue.
