X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2e498f25b0daa9dec761e3e880024ff7417f2445;p=linux-beck.git

target: Fix incorrect unmap_zeroes_data_store return

This patch fixes an incorrect return of zero from the new
unmap_zeroes_data_store() configfs store attribute handler
introduced in v4.5-rc1, to use the correct 'count' bytes
return value.
