From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chanwoo Choi Subject: [PATCH] Input: stmfts: Fix bug of ABS_MT_POSITION_* maximum size Date: Wed, 18 Oct 2017 19:38:30 +0900 Message-ID: <1508323110-10061-1-git-send-email-cw00.choi@samsung.com> References: Return-path: Sender: stable-owner@vger.kernel.org To: dmitry.torokhov@gmail.com Cc: rydberg@bitmath.org, andi.shyti@samsung.com, robh@kernel.org, arnd@arndb.de, cw00.choi@samsung.com, chanwoo@kernel.org, inki.dae@samsung.com, sw0312.kim@samsung.com, linux-input@vger.kernel.org, linux-kernel@vger.kernel.org, linux-samsung-soc@vger.kernel.org, stable@vger.kernel.org List-Id: linux-input@vger.kernel.org The commit 78bcac7b2ae1e ("Input: add support for the STMicroelectronics FingerTip touchscreen) used the 'touchscreen_parse_properties()' helper function in order to get the value of common properties. But, commit 78bcac7b2ae1e didn't set the capability of ABS_MT_POSITION_* before calling touchscreen_parse_properties(). In result, the max_x and max_y of 'struct touchscreen_propeties' were not set. So, this patch fixes the bug to get the ABS_MT_POSITION_* maximum size.
