linux.git/drivers/tty/serial/of_serial.c, branch v3.2 Linux kernel source tree drivercore: Add helper macro for platform_driver boilerplate 2011-10-24T22:35:47+00:00 Grant Likely grant.likely@secretlab.ca 2011-10-05T17:29:49+00:00 940ab88962bc1aff3273a8356d64577a6e386736 For simple modules that contain a single platform_driver without any additional setup code then ends up being a block of duplicated boilerplate.

drivercore: revert addition of of_match to struct device 2011-05-18T18:32:23+00:00 Grant Likely grant.likely@secretlab.ca 2011-05-18T17:19:24+00:00 b1608d69cb804e414d0887140ba08a9398e4e638 Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
