* watchdog: Get rid of MODULE_ALIAS_MISCDEV statementsJean Delvare2013-11-171-2/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR) and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements. Either the device is enumerated and the driver already has a module alias (e.g. PCI, USB etc.) that will get the right driver loaded automatically. Or the device is not enumerated and loading its driver will lead to more or less intrusive hardware poking. Such hardware poking should be limited to a bare minimum, so the user should really decide which drivers should be tried and in what order. Trying them all in arbitrary order can't do any good. On top of that, loading that many drivers at once bloats the kernel log. Also many drivers will stay loaded afterward, bloating the output of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets loaded as a dependency) can't even be unloaded! If defining char-major-10-130 is needed then it should happen in user-space.

* powerpc/wdrtas: Update wdrtas_get_interval to use rtas_data_bufMark Nelson2009-04-071-2/+11
| | | | | | | | | | | | | | | The buffer passed to the ibm,get-system-parameter RTAS call must be in the RMA. To ensure we pass an address in the RMA use rtas_data_buf for the actual RTAS call and then copy the result to value. We can't just make it static because this can be compiled in as a module. Also add the WDRTAS_SP_SPI_LEN so we don't litter '4' throughout the function.
