Subject: PATCH: drivers/staging/lirc/lirc_serial.c: use IS_ERR()
Date: Sun, 06 Feb 2011 15:39:29 -0500 [thread overview]
Message-ID: <4D4F0701.5060602@teksavvy.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 725 bytes --]
The lirc_serial.c module has never worked with ordinary homebrew
serial blaster hardware, and leaks memory when this is attempted.
Fix it by replacing incorrect usage of PTR_ERR() with IS_ERR().
(patch is inline and also attached to bypass mailer issues).
