From: Oded Gabbay Date: Tue, 13 Jul 2021 05:11:54 +0000 (+0300) Subject: habanalabs: revise prints on FD close X-Git-Tag: v5.15~302^2^2~35 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a6cd2551d7874ce276ff64348471a9e22ce35020;p=platform%2Fkernel%2Flinux-starfive.git habanalabs: revise prints on FD close The driver quietly handles memory mappings that were not freed so no need to print a warning about that when user closes the FD. Accordingly, revise the text that is printed in case the device is still in use after the user process closed the FD.
