2012-09-19HID: picolcd_core: Remove setting hdev->claimed before calling hid_hw_start()Axel Lin1-4/+0
Current implementation of hid_hw_start() allows connect_mask to be 0. Setting hdev->claimed = HID_CLAIMED_INPUT before calling hid_hw_start() is not necessary. Remove it.

2012-09-19HID: picoLCD: drop version check during probeBruno Prémont1-18/+0
Commit 4ea5454203d991ec85264f64f89ca8855fce69b0 [HID: Fix race condition between driver core and ll-driver] introduced new locking around probe/remove functions that prevents any report/reply from hardware to reach driver until it returned from probe. As such, the ask-reply way to checking picoLCD firmware version during probe is bound to timeout and let probe fail. Drop the check to let driver successfully probe again (until locking issues are resolved allowing to reinstate the check).

2012-09-05HID: picoLCD: prevent NULL pointer dereferencesBruno Prémont1-1/+1
Driver code expects to get access to struct picolcd_data from hiddev and is not prepared to find a NULL pointer there. Most prominent candidate to trip on it is picolcd_fb_deferred_io(). Delay removing struct picolcd_data from hiddev until all sub-devices have been unregistered. Signed-off-by: Bruno Prémont <bonbons@linux-vserver.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

In order to make code maintenance easier, split the vairous functions into individial files (this removes a bunch of #ifdefs). Signed-off-by: Bruno Prémont <bonbons@linux-vserver.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
